In middle school, Shizuku was known as the girl with the toughest guard in school. She was so guarded that she would coldly brush off even other girls, and because she was beautiful enough that every boy dreamed of dating her, countless boys tried to win her over only to face immediate defeat.

Now a high school student, the undefeated Shizuku is still known for her ironclad guard, but another figure has emerged. That person is Guest, who, just like Shizuku, absolutely refuses to fall in love.

Despite numerous confessions, Guest rejects them all. They are two of a kind, parallel lines that should never intersect no matter what.

One day, as they start their third year of high school, these two end up in the same class. Shizuku, who will never love, and Guest, who will never love. Will their parallel worlds ever meet?
