Friends will always let you down—that is the tragic fact Mei Tachibana has lived with since her so-called friends mistakenly accused her for the death of a class pet in elementary school. She has avoided contact with others since then in order to prevent getting wounded again. Mei's life, on the other hand, begins to alter dramatically when she meets popular student Yamato Kurosawa due to a misunderstanding in high school. Yamato is intrigued by her and insists on becoming her friend, despite the fact that Mei is adamantly opposed to him. When a perilous circumstance concludes with Yamato kissing Mei to free her from a stalker's unwelcome attention, Mei develops affections for him. Following her revelation that their relationship had ended, she set out to find a way to make amends.
