"Um... I came across this word on the encyclopedia recently, but I didn't quite understand it. Since I have the opportunity to meet a professional like you, I wanted to ask for your guidance."

After hesitating for a while, Chongzong came up with a feeble excuse, but to his surprise, the Yaksha Nurse didn't use it to question him.

"Well, I'll reluctantly give you an answer then."

The Yaksha Nurse smiled mysteriously, then proceeded to walk swiftly with her meteor-like stride, answering Chongzong's question as she walked.

"Stretch marks, not all pregnant women will have them. Those with good skin elasticity and proper weight control during pregnancy may not develop stretch marks."

"Commonly, stretch marks appear on the abdominal wall, but some female friends may have stretch marks on the inner and outer thighs, buttocks, chest, back, shoulders, and arms. Comparatively, there will be fewer on the abdominal wall."

"As for eliminating stretch marks after childbirth, it is quite difficult. Generally, they can be lightened, but completely getting rid of them is basically impossible."

"Do you understand, young man? Do you have any more questions?"

The Yaksha Nurse glanced at Chongzong and slightly increased her walking speed.

"No, thank you, Nurse. My doubts have been cleared. Goodbye~"

Chongzong slowed down his pace, bowed slightly to the departing Yaksha Nurse, and turned back to the school.

— Now, all that's left is to confirm if that woman has stretch marks or not.

Changing his address from "Ayaki Yuriko" back to "that woman," Chongzong was well aware that at the moment, he needed to figure out which information on that woman's belongings was true and which was false.

After more than half an hour, Chongzong returned to the school library. In the corner, Eiji Hayamizu was diligently writing, accompanied by another person wearing a different school uniform.

— I remember her name was... Oni... something?

Chongzong remembered this girl. She was Eiji Hayamizu's girlfriend (or one of them) and seemed to be older than him. She was from a nearby high school, possibly a first-year student.

— Wait? Or was it second-year? I don't remember...

While trying hard to remember, Chongzong walked towards them.

Eiji Hayamizu was immersed in the pleasure of solving problems, but the girl beside him noticed Chongzong's approach first.

"Oh? Isn't this Uesugi Chongzong? Little brother, right?"

An unexpected and damaging attack (verbally) suddenly struck Chongzong's heart, bringing back the scene of their initial encounter.

Her shoulder-length hair was slightly curly, casually falling onto her shoulders as if it had been brushed. She was wearing the uniform of Liwan Industrial High School - a white shirt, tie, black coat, and knee-high socks, a more mature look compared to her middle school uniform.

It had been some time, but it was spot-on.

Thanks to this "Uesugi Chongzong, little brother," Chongzong also remembered this girl's exact name.

"Just call me Uesugi, Kikuzura-senpai."

"I never expected you to remember me, Uesugi, little brother. I'm glad~"

Ignoring Chongzong's request, Eiji Hayamizu's girlfriend (or one of them?), Onitsuka Kaori, happily taunted Chongzong.

The voices of their conversation finally brought Eiji Hayamizu back to reality and he noticed Chongzong's return.

"Ah, Uesugi, you're back!"

Eiji Hayamizu said, glancing at the time on his phone.

"There's still half an hour left until the deadline, but I can finish in another ten minutes! Hmph!"

Before Chongzong could respond, Eiji Hayamizu lowered his head and returned to the embrace of the exercises.

Chongzong walked over and quickly glanced at Sugimizu's progress, feeling very relieved. He had improved from a kindergarten level to sixth grade, it was truly impressive progress.

--- In a little while, he would reach the level of a third-year junior high student, and going on to higher education would not be impossible. Congratulations were in order.

In contrast to Chongzong, who had an expression of contentment on his face, Onitsuka Kaori was already displaying her displeasure and anger, fully attributing it to Chongzong as the culprit.

When Chongzong noticed Onitsuka Kaori's hostile gaze, he realized that there was a disaster in front of him that needed to be resolved.
