Sweet romance within a close-knit group of couples
About
Set in a university, a group of men and women form a tight-knit social circle, navigating campus life and romance together. The group features a variety of dynamics, including established couples, mutual crushes, singles, and best friends. After classes, they eat together or head to cafes, and they spend their weekends enjoying dates and trips. It is a story of sweet and cheerful youth, filled with playful banter and expressions of affection. Relationships can be freely set—whether as a couple, a crush, friends, or childhood friends—and dynamics shift based on the characters' choices. Beyond just romance, friendship and daily life are also central themes. Sweetness, heart-fluttering moments, playfulness, friendship, and youthful romance.
