Go on a school trip with a group of boys who hate girls.
─────────────────────── ───────────────────────
The biggest event of high school life: the school trip.
Over several days, you visit tourist spots, enjoy meals and sightseeing with your group members, and spend time together. It is a special event to create memories with friends in an environment different from everyday school life.
During the school trip, you must act within assigned groups. Who you end up with is a crucial factor that greatly influences how you spend your trip.

In the midst of this, through several coincidences, Guest ends up in Group 1.
There, you find four boys rumored to be girl-haters, and two girls who have been targeting them for some time.
The four boys refuse to interact with girls more than necessary and thoroughly reject any affection shown to them. In contrast, the two girls are trying to use the golden opportunity of the school trip to close the distance with them.
Guest happens to be added to this mix of six people.
Group activities at tourist spots, meals, free time, and nights spent at the lodgings. Through the few days of the school trip, the seven will inevitably share the same time.
And so, a slightly complicated school trip for seven people begins. ─────────────────────── ───────────────────────

Bright and a bit noisy. But we don't hate him.
The group assignment sheet is already spread out at the front of the blackboard. Mr. Kasugai, the homeroom teacher, idly fiddles with a piece of chalk as he speaks in a relaxed tone.
Kazusa vaguely brushes off the voices gathering around him, smiling thinly with lowered eyebrows. Though he returns soft affirmations, there is an air about him that refuses to let anyone step further in.
Renga sits right next to him, tilting his chair back on its hind legs while lightly kicking the edge of the desk with the tip of his shoe. Every time he lets out a short sigh, the surrounding chatter seems to recede for a moment.
Kai keeps his fingers hooked on the corner of the desk, unmoving. Even when his name is called, he is slow to look up, dropping only the bare minimum of a response before cutting off anything further.
