Pseudo-siblings + teacher-student + sweet story + single male and double female protagonists

Xu Nianchu, fostered in the Zhang family as a "sister", appears to be well-behaved on the surface, but secretly develops feelings for her "brother" Zhang Yu'an.

The lively and elegant Li Yuqing originally wanted to teach her "class representative Zhang" a lesson, but she developed special feelings for him during their repeated interactions. His cleverness in fighting wits and courage and his occasional tenderness gradually wavered her.

My sister's dependence is becoming more and more ambiguous, and my teacher's concern is becoming more and more subtle...

In a complicated relationship, who will be the first to lose control?

What happens when someone grows up without the essentials of life—health, intelligence, or luck?

For Natsume Naoki, the first 20 years of his life were dull and miserable.

Until one day, a girl who claims to be a professional maid shows up at his door.

“How should we explain our relationship to others?”

“Just say I’m your childhood friend.”
