……

June marks the beginning of summer.

Under the scorching sun, almost no one is willing to go out unless absolutely necessary.

"...That's the basic information. Let's set it for tomorrow; I need you to come to the club to deliver my lunchbox, understand?"

A rather flat-chested blonde girl looked at the devastatingly handsome boy in front of her, who was just as handsome as the readers, and spoke rather coldly.

"No problem, please rest assured of my professional ethics, Ms. Sawamura. I am very professional, the number one rental boyfriend on the list."

Looking at Eriri, He Qian was holding a phone and writing something down, then replied with a smile.

Hearing this, Eriri nodded in satisfaction and then left.

Seeing the other person leave, He Qian shook his head, then sighed softly:

"Hey."

For a transmigrator to have to be someone else's rented boyfriend is truly a disgrace!

That's right, He Qian is a time traveler.

Moreover, he was transported to an extremely mixed world.

This place features not only heroines like Eriri, Kasumigaoka Utaha, and Megumi.

It also features characters such as Kaguya Shinomiya, Mashiro Shiina, Yukino Yukinoshita, Shoko Toyokawa, and even Sora Kasugano.

But none of this has anything to do with He Qian.

He had only one thought: to return to the world he once knew.

After all, He Qian lived a very happy life in her original world.

It can be said that almost 99% of the people who have already won the lottery are now truly 'winners in life'.

It didn't feel like living in this broken world at all; life was incredibly difficult.

At the beginning, He Qian's life was a true 'wilderness survival'.

After all, He Qian transmigrated directly in his physical body, only his age was reduced.

His developmental stage was roughly equivalent to when he was 18 years old in his previous life.

Now, things are only slightly better; we can barely make ends meet.

"System, are you sure that collecting the energy of so-called 'high-quality women' will help me go back?"

After sighing, He Qian looked at the information about their club that Eriri had just mentioned on his phone and thought to himself.

That's right, he also has a system.

Otherwise, He Qian would probably have starved to death long ago, given that his physical body had just transmigrated to this world.

I remember that as soon as the system woke up, it gave me a newbie gift pack.

The package includes Japanese language skills, a basic form of identification, and a job as a rented boyfriend.

As for anything else, there's nothing.

[Please rest assured, host. As long as you complete the mission and obtain enough energy, I will certainly be able to help you return to your original world.]

"alright."

Hearing the system's words, He Qian nodded, and then couldn't help but ask:

"So why did I have to become this rented boyfriend?"

The reason he came to be this damn rented boyfriend is...

This is naturally also due to the system's arrangement.

Because only 'high-quality women' can generate energy.

As for the process of energy generation, it requires you to guide the other person's emotions, whether it's joy, anger, sorrow, or resentment. As long as it's something that affects you, you can collect energy.

[Given that the host's goal is to return to the original world, the system detected that this objective requires a large amount of energy, and therefore chose the profession of 'renting a boyfriend' which allows interaction with many 'high-quality women'.]

Please stop wondering why this profession was chosen; it's the optimal result calculated by the system based on the Great Wisdom model.

"Then I'll believe your so-called wisdom."

Hearing the system say this, He Qian naturally had no objections.

He was just looking at the basic information Eriri had just mentioned on his phone.

Actually, there's not much need to watch it. At least He Qian knows the general plot of the famous "Ghost Story" from his previous life.

However, all of this information was provided by Eriri herself.

He Qian was able to use these clues to judge Eriri's general thoughts.

"According to her own words, it's because of a certain sharp-tongued guy in the club... it should be Kasumigaoka Utaha. Utaha is so sharp-tongued that someone with Eriri's personality might never find a good boyfriend in her life. That's why she chose me, the number one 'rent-a-boyfriend' on the list, to slap her in the face."

"But actually, it's probably still to provoke Aki Tomoya, right?"

Thinking about what Eriri had just said to him, He Qian understood everything.

The other party specifically sought him out to make Aki Tomoya feel a sense of crisis.

"In that case, don't blame me for being impolite!"

Thinking of this, He Qian was also delighted and had a mature idea.

After all, the system said that to guide the emotions of these so-called 'high-quality women,' the main thing is to collect energy from the emotions they generate.

But for Eriri, who is a tsundere.

What is easier to evoke than the emotion of 'love'?

Of course, there must be a balance to be struck in this process.

Ideally, Eriri should be made to hesitate about her relationship with Aki Tomoya.

Then He Qian himself 'discovered' this point.

In order to get rid of Eriri.

"Aki Tomoya, don't worry, I'm just showing off to you temporarily. Once I've gathered all the energy, I'll disappear immediately!"

Having made up his mind, He Qian decided to go home.

Just then, the phone rang.

He Qian was speechless when he saw the nickname "sister" displayed on the caller ID.

However, the call was answered immediately:

"Qiong... what's wrong?"

"Come back quickly, I'm hungry."

After hearing the girl's light, airy voice on the other end of the phone, the call was immediately disconnected.

He Qian didn't seem to care much about this.

Because of the identity given in the newbie gift pack by the system.

He, He Qian, came to Sakurajima with his single mother.

After arriving at Sakurajima, He Qian's adoptive mother got together with Kasugano Sora's single father.

Unfortunately, their relationship didn't last long before they were killed in a car accident.

Moreover, because it was entirely the responsibility of He Qianbian's parents, they had to sell the house they had left behind to barely make up for the debt.

Of course, all of this was just He Qian's basic setup before he transmigrated here.

He didn't have much of an impression of his adoptive mother.

But Kasugano Sora is completely different.

The other party was indeed identified by the system as a 'high-quality woman'.

He Qian's first pot of gold was provided by the other party.

It is precisely because of this that he has been able to go from 'surviving in the wilderness' to barely making ends meet.

Therefore, He Qian treated Kasugano Sora very well, and even planned to make an effort to ensure that she could live a life free from worries about food and clothing before leaving.
