I became a girl group idol for my sister.

“No need, splitting the bill is fine. Besides, you’re still a graduate student, so you don’t have much income, right?” Sakagami Minami said.

This made Miyamoto Sei shut his mouth.

Without using the inheritance left by his parents, he doesn't have much money right now, and the basic salary for a graduate student is only 5 yen a month. Although there is a performance fee for the performance, the first performance of the ninth generation of graduate students is not until a month later.

However, just as Miyamoto thought it was time to go out, Sakagami Minami first put on a mask, then a hat, and after disguising herself, she turned around and winked at Miyamoto: "Let's go."

"This is……"

"It would be troublesome if the fans recognized us. Just getting autographs would probably take up a lot of time." Sakagami Minami smiled, pushed open the door, and walked out.

Because it's an employee access area, you won't see many fans or similar people here; they usually stay near the theater entrance.

Upon arriving at the KTV private room and seeing Sakagami Minami already sitting on the sofa, Miyamoto Sei still felt a little unreal.

He was currently alone with Sakagami Minami, who was considered a national idol, in a karaoke room. If he told those guys at school, they would definitely say he was dreaming.

But this is reality now, not a dream.

“Sometimes when I want to practice singing but there’s no available practice room, then I have no choice but to come to a karaoke bar. After all, it would disturb the neighbors if I stayed at home.” Sakagami Minami said, gently smoothing her hair with her right hand. “Why don’t you give it a try first? I’ll listen carefully and see what problems you have.”

"Then I'll make a fool of myself."

He picked up the microphone, requested his most familiar song, "The Beginning," and Miyamoto Sei opened his mouth.

Sakaue Minami listened to Miyamoto Se's song. She was very familiar with it because she often sang it; after all, it was one of the main songs of the girl group SKR.

Sure enough, it sounds awful.

There were absolutely no techniques involved; I was just singing randomly based on my own feelings.

However, it's not entirely without merit, because even if the singing lacks technique, the singer's emotions are still present in the song.

If this feeling can be truly embodied and conveyed to the recipient, then the song has already been sung successfully to some extent.

Sakagami Minami listened intently, lost in thought, without interrupting.

After finishing the song, Miyamoto looked at Sakagami Minami with some unease.

"How was it, Senior Nan?"

"Your vocalization is problematic and needs to be changed. If we're talking about the most basic aspects... how about using some unconventional techniques?"

As if in response, or perhaps to herself, Sakagami Minami lightly nodded her right finger to her lips, then suddenly stood up.

"Huh? Senior, what are you doing?!"

Miyamoto Sei's hand was grabbed by Sakagami Minami, and he was laid down on the sofa, with Sakagami Minami straddling him.

“Of course it’s for training,” Sakagami Minami said, pressing her butt against Miyamoto Sei’s stomach, and placing her left hand on his throat. “I’m going to start playing a song now, and you try your best to sing it!”

Holding the remote control in her right hand, she turned on "The Beginning" again, and Sakagami Minami just stared at Miyamoto Sei.

"Make sure you open your mouth wide, otherwise you won't achieve the desired effect from the practice!"

"This, this kind of training..." Being suppressed by an idol like this, Miyamoto felt that his rationality was being put to a great test, but he absolutely could not react at all.

I am a woman now! I am a woman now!

Despite constantly hypnotizing herself, Miyamoto Sei continued to struggle.

"The song has already started. If you want to master singing skills as quickly as possible, then I think this is the best way. Nana-chan, you want to master singing skills as soon as possible, right?"

The question stopped Miyamoto Sei from his struggle. He wanted to master the singing technique, but now his senior, who was so good at singing, was teaching him during his break, while he was still thinking about other things. This made him feel a little guilty.

"I can sing, senior!"

Accompanied by music, Miyamoto Sei began singing "Hatsuhin" once again.

His voice was completely different from when he was standing. Under the pressure of Sakagami Minami's buttocks and hands, he felt the changes in his throat and abdomen. The air was squeezed out of his lungs without any obstruction, flowed smoothly through his throat, and then turned into singing.

After the song ended, he remained there in a daze, not even noticing that Sakagami Minami had left him.

Even though I hadn't had any special training, the feeling I just experienced was completely different from my usual singing level.

"Remember that feeling from just now. There are many singing techniques, but there are a few key points, such as pronunciation. If I just tell you, it might be hard to learn. So remember the feeling of that sound and make it your instinct."

Sakagami Minami gave Miyamoto Sei a thumbs up.

"And what you need is confidence, you must be confident, don't be afraid to sing it out, after all, you are very talented, Nana-chan."

"I...I have talent?"

Miyamoto looked at Sakagami Minami with some disbelief, thinking to himself that without the Heavenly Demon Voice as a foundation, he couldn't even produce a female voice. What kind of talent was that?

"Infectiousness, the most important thing in singing is not technique, nor is it singing without any problems, but the communication, conveying your own feelings about the song, letting the audience and fans feel your sincerity. That is the most crucial and important point."

Sakagami Minami's words stunned Miyamoto Sei, who never expected that Sakagami Minami would tell him that the most important thing was to convey emotions, not techniques.

"Wait a minute, I'll show you a video."

As she spoke, Sakagami Minami turned on her phone and opened a webpage to search for something. Miyamoto Sei didn't look at it, so as not to see the other person's privacy.

"Look, this is it. Tell me your thoughts after you've read it."

Sakagami Minami handed the phone to Miyamoto Sei, who glanced at it and saw that it was on YouTube and a video was already playing.

The image above shows a middle-aged man who looks like a beggar. He is currently holding a guitar, playing music and singing.

With his disheveled appearance and not-so-pleasant voice, and his singing technique being quite ordinary, there was something about him that made it hard to look away. This song instantly captured Miyamoto Sei's attention.

Even though the technique isn't great, why is it so appealing?

I even felt like crying...

Feeling a lump in her throat, Miyamoto wiped her eyes slightly and silently watched the one- or two-minute video.

"Do you understand now?" Sakagami Minami looked at Miyamoto Sei with a hint of expectation in her eyes.

"He conveyed genuine emotions, didn't he?" Miyamoto asked, then added, "I felt those emotions, very real emotions. You could feel his experiences. It wasn't just the lyrics, but the music also resonated with him so much that you couldn't help but be drawn into it."

"That's what charisma is, and Nana-chan, you're incredibly charismatic too! That's your talent! So, be confident in yourself and don't be afraid to sing!"

I haven't truly become an idol yet, I haven't truly stepped onto the idol stage, I don't have these experiences, so where does my charisma come from?

Could it be that some other emotions were involved?

No, it's not just other similar emotions. There's probably also the effect of the Heavenly Demon Sound. Even though its power is greatly weakened, it's still given by the system. It can't completely control people's hearts, but it can still convey its own emotions.

So, I guess this can be considered my talent. I seized the boost brought by the Heavenly Demon Sound and then continued to work hard to improve my skills on that basis.

"But we can't let our guard down. Although our SKR girl group isn't exactly known for its singing, we still need to improve our weaknesses so as not to hold the group back."

"Thank you so much, Senior Nan. You've really helped me a lot today. Please don't hesitate to ask if you ever need anything from me in the future!"

"Alright, we still have plenty of time, so let's move on to the second song. This is our Team S's signature song, do you want to give it a try?"

"But I haven't learned it yet!"

"It's okay, it's okay, just sing along. Since you're in SKR, you should definitely try to familiarize yourself with the songs of each team, especially the ones you'll definitely be performing. That's advice from your seniors!"

"Yes, senior, it's wonderful to have Senior Nan teach me to sing. I will definitely memorize all the main songs!"

"Oh, really? Hehe, I'm almost embarrassed to say that."

So, she tried out song after song, trying her best to remember that initial feeling. When Miyamoto Sei said goodbye to Sakagami Minami and returned home, it was already past nine o'clock at night.

"I'm back……"

"Welcome back, brother."

Miyamoto saw Yukiko Miyamoto sitting on the sofa staring at him with wide eyes.

"What's wrong? Are you waiting for me to have dinner?"

"No, I made some myself, but you came back too late, brother." Miyamoto Yukiko looked at Miyamoto Sei curiously, got off the sofa, and walked over to sniff him.

"That's strange, brother, do you still like to wear perfume now? And why do you smell of sweat? Ah, go take a shower!"

Pushing Miyamoto Sei towards the bathroom, Miyamoto Yukiko frowned: "Your girlfriend will dislike you if you act like this!"

"What girlfriend? I'm working, okay? I'm working really hard!"

Defending himself, Miyamoto Sei broke free from Miyamoto Yukiko's control, opened his bedroom door, put the backpack containing women's clothing inside, and then headed towards the bathroom.

"I'm going to take a shower now. Did you really eat?"

"You really ate it!"

"What to eat?"

"I chopped some tomatoes and then made some bread."

Miyamoto stopped what he was doing and turned his head to look at his younger sister.

"Wait until I finish showering. I need to have dinner later, so let's eat together then."

"Yay!" Yukiko Miyamoto cheered and sat down on the sofa, even singing softly, "Dinner, dinner, my brother's dinner!"

On the television, there were advertisements for beverages featuring Sakagami Minami and others.

As the door closed, Yukiko Miyamoto poked her head out from behind it.
