As a symbiotic being, I raise children amidst the chaos.

My name is A-310. Normally, after finishing my lessons and training, I would be obediently taken back to my room to wait for the next day to begin. But today, things were a little different.

"A-310, Lord Otto will be coming to check on your progress in a little while. Don't be nervous, just do what you normally do." (Note: Theresa doesn't have this name yet; her code name is A-310. But for the sake of reading experience, we'll use Theresa's name for now.)

"Understood..." Hearing the researcher's words, Theresa smiled and nodded, then skipped back to her room. Seeing the obedient Theresa, the researcher breathed a sigh of relief and slowly left.

But what the researcher didn't know was that in the instant she turned around, Theresa gave a mischievous grin, pressed her ear against the door, and listened intently to the sounds outside. "Gone?"

"Hmm...they're gone." Chen Yuan whispered, resting his head on Theresa's head. "There's no one outside."

"Really? That's wonderful!" Hearing Chen Yuan's words, Theresa jumped up happily, and gently pulled a comic book from her pocket. "Hehe, now I can read comics without worry... Hmm?"

At that moment, Theresa suddenly felt that something was wrong, but she couldn't quite put her finger on it. She looked back but didn't see anything unusual. When she turned her head back, she found Chen Yuan sitting on her comic book, waving at her.

"A ghost!!!!" Upon seeing Chen Yuan, Theresa's eyes rolled back and she immediately lay down. Theresa's scream echoed throughout the corridor, but fortunately, the researchers had already left, otherwise, that scream would probably have caused quite a bit of trouble.

Seeing this, Chen Yuan quickly jumped down from the comic book, floated in front of Theresa, and waved his little hand in front of her face. "It can't be that scary... Am I that frightening?"

Meanwhile, after returning to his room, the researcher sat down at his desk to organize the data he had recorded that day. He then skillfully opened the communication app, and a blond, blue-eyed young man appeared in the video.

"Good evening, Bishop Otto. The data for today's A-310 has been sent to you."

"Yes, I'm looking at it now. Thanks for your hard work." Opening the data, Otto meticulously reviewed Theresa's every move of the day, a smile unconsciously playing on his lips. 'So...so alike...'

“Um…Bishop Otto? Is there a problem?” Seeing Otto remain silent for so long, the researcher broke out in a cold sweat and asked nervously, “Or are you not satisfied with the training or courses A-310 is currently undertaking?”

“No, for now, I’m very satisfied. You’ve done a good job.” The researcher’s words pulled Otto back to reality. After clearing his throat twice, he continued, “Have you delivered the comic books I asked you to prepare to A-310?”

"Yes, it has already been taken by A-310, without her realizing that we deliberately left it there for her to take."

"Hmm, well done." Hearing Otto's affirmation, the researcher visibly relaxed, then continued, "Thank you for the praise, Bishop Otto. So, what's next? Should we adjust tomorrow's course content?"

"No need, continue with the original plan. Also, remain vigilant. If she does anything unusual, notify me immediately."

After hanging up the call, Otto stood up and slowly walked to the window, gazing at the night outside. His heart was filled with complex emotions; whether it was joy or sorrow, even Otto himself wasn't sure. Finally, only a sigh escaped his lips: "Kallen... is that you?"

At this moment, Theresa was lying on the ground, curled up in a ball, looking at Chen Yuan with a frightened expression. Chen Yuan, on the other hand, sat innocently not far away, saying, "I mean, is it really necessary to be so afraid of me? I'm not bad-looking, am I?"

"Indeed... she's much prettier than those uncles and sisters who taught me." Theresa heard Chen Yuan say this, moved closer to look, nodded seriously, and then quickly crawled backward. "But no matter how pretty you are, you're still a ghost!!"

"Everyone says I'm not a ghost!! I have a body, okay? Feel it if you don't believe me!" Chen Yuan sighed helplessly and jumped in front of Theresa. "I'm just... well, how should I explain it? You can think of me as a special kind of life form, like a guardian in a fairy tale."

Although Theresa was still shaken, her curiosity gradually took over after hearing what Chen Yuan said. She cautiously reached out and touched Chen Yuan's body, only breathing a sigh of relief when she felt the solidity in her hand.

"So you really aren't a ghost!" Theresa relaxed, a smile playing on her lips. She sat up, brushed the dust off her clothes, and looked at Chen Yuan, saying, "Then why did you scare me just now? Don't you know ghosts are the scariest things?"

"Who scared you? You're just too timid, aren't you?" Chen Yuan rolled his eyes at Theresa, cleared his throat, and continued, "Although it's a bit late, my name is Chen Yuan."

“A name… I don’t have a name right now…” Theresa’s face fell, but she quickly recovered and regained her cheerful demeanor. “But I have a code name, everyone calls me A-310.”

"A-310, that's a pretty good codename..." At this point, Chen Yuan seemed to recall something, a smile playing on his lips. "How about this... I help you come up with a new name?"

Theresa paused for a moment, then her eyes lit up, and she asked curiously, "Really? You can help me name it?"

Chen Yuan nodded, a hint of a smile flashing in his eyes: "Of course. Everyone has their own name, a unique identifier. Would you like me to help you choose a name?"

Theresa hesitated for a moment, then finally nodded. "Okay, I believe you," Theresa said softly, a hint of expectation in her eyes. "You have to give me a nice name, okay?"

"Something nice-sounding, right? Let me think." Just kidding, is there even a need to think? If we're going to choose a name, this is the only one we have!

Thinking of this, Chen Yuan reached out and gently tapped Theresa's forehead with his finger, saying softly, "Then, from today onwards, you will be called 'Silly Theresa'."

"Theresa?"

"No, it's Deli who's stupid!"

"Theresa, Theresa... What a beautiful name, I love it!!" Ignoring the last part of Chen Yuan's sentence, Theresa happily jumped around the room.

Seeing that he hadn't achieved his goal, Chen Yuan wasn't disappointed; he'd only intended to tease Theresa anyway. Theresa is, after all, Theresa…

However, seeing Theresa smiling happily always reminded Chen Yuan of the time when he first took care of Seele and Xing at the Cocolia Orphanage.

When it comes to raising daughters, Otto, you're still far from being as accomplished as I am! Although you're raising a granddaughter, and my daughters have been a bit skewed too, they're definitely much better than this guy who keeps talking about Karen all the time!

"Knock! Knock! Knock!" Just then, a knock came at the door, followed by the voice of the researcher who had just brought Theresa back. "A-310, please open the door. Bishop Otto has come to visit you."

Speak of the devil, and he appears. Shaking his head helplessly, Chen Yuan beckoned to Theresa, who quickly came over. "As payment for the name, you can't tell anyone about me!"

Although the system said that no one or nothing could see its existence, that was for ordinary people. As for Otto, Chen Yuan had no confidence at all.

That's absurd! It's not easy to have such an opportunity, wouldn't it be a waste not to make good use of it! Thinking of this, Chen Yuan revealed an extremely wicked smile.

“Theresa understands!” Theresa nodded gently and ran to the door. With a 'bang,' she opened the door, and Otto, dressed in a white suit, slowly walked in. The researcher gently closed the door and waited at the doorway.

"A-310, long time no see." Otto smiled involuntarily when he saw Theresa, and knelt down to pat her head. "Are you happy living here?"

"Thank you for your concern, Bishop. I am living very well here and do not feel anything is wrong." In a completely different manner from when she was with Chen Yuan, Theresa seemed to have suddenly transformed from a child into a lady in front of Otto.

"Really? That's good..." Otto stood up, about to say something, when he saw Theresa looking at him with a... strange expression, like a human trying to suppress a laugh. "A-310, is there something on my face?"

"Pfft... No, Your Excellency, there's nothing on your face..." Theresa reached behind her back and pinched her flesh hard to prevent herself from laughing.

From her perspective, as Otto crouched down, Chen Yuan slowly climbed onto his body, poked his cheek with her finger, and said mysteriously, "Shh! Don't talk, keep quiet. I'm observing Bishop Otto. Hmm... really handsome, but not quite as good as me."

Theresa couldn't help but want to laugh, but she was afraid that Otto would find out, so she had to hold it in.

"What are you doing?" Otto frowned slightly, leaned down, and tentatively approached Theresa. His eyes held concern, but something else was hidden beneath. "Did you...see something?"

"N-no...no!" Theresa quickly shut her mouth, forcing herself to look innocent. "I just thought...adults are always so serious, and I wanted to see if there was anything strange..."

At this point, Theresa couldn't hold back any longer and burst out laughing. Then, Chenyuan appeared atop Otto's head in an extremely flamboyant pose and began to sing loudly.

"How lonely it is to be invincible..."
