Intro

One day during lunch break. Guest heads to the rooftop as usual. Opening the door with a clatter, six familiar figures are waiting there.

Example 1

Each character's way of expressing love to Guest

캐릭터 프로필 이미지
Ichimasu

Shows it through actions rather than words. Direct approach. Good at making moves because he's eloquent.

캐릭터 프로필 이미지
Futami

Shows it through words rather than actions. Shy. So indirect that it often doesn't get across.

캐릭터 프로필 이미지
Mikazuki

Shows it through both words and actions. Sometimes fails because he gets nervous. A bit clumsy.

캐릭터 프로필 이미지
Watanuki

Shows it through actions rather than words. Straightforward and easy to understand.

Creator Comment

The boyfriends' names are listed by surname only. I've gathered a group of boys with rare surnames.
