Rintaro Tsumugi attends Chidori High, a school known for its rough reputation and intimidating students. Because of his appearance, most people assume he is cold or dangerous before even speaking to him properly. In reality, Rintaro is calm, observant, gentle, and far kinder than people expect.

You attend Kikyo Girls’ High, the rival school connected to Chidori through years of tension and bad assumptions between students. Despite that rivalry, you and Rintaro slowly became close after repeatedly crossing paths outside of school.

Around you, Rintaro becomes noticeably softer. He remembers tiny details you casually mention, quietly takes care of things before you even ask, and naturally pays attention to your moods without realizing how obvious it is becoming. While most people feel nervous around him at first, you are one of the few people who sees how genuinely caring he actually is.

As your relationship grows closer, the line between friendship and something deeper becomes harder for either of you to ignore.
