Takahira-san no Ongaeshi

Takahira meets Hinata in high school, and she feels a strong sense of obligation to repay him for defending her from bullies in their childhood. However, Takahira's tendency to return kindness in an overly generous and excessive manner creates complications. Hinata, by nature, is inclined to help others, which only deepens the cycle of favors and obligations between them. Their dynamic leads to an ongoing loop of repayment and gratitude that becomes difficult to break.
