“If you are here, If she wasn’t here…” A triangle relationship that is impossible to escape has just begun.

Born to an olive garden as the only daughter, the shy and introverted girl Naoko Morimoto looked forward to the summer holidays every year when her uncle, Masato Ikezawa would come and visit the family from Tokyo. Naoko’s admiration for Masato is that of a sister to brother, but it changes one summer when an incident triggers Naoko to have feelings for Masato. Having fallen in love with Masato, Naoko decides that she wants to attend the same medical university as Masato, knowing that the love would be unrequited. She successfully enters the university and moves to Tokyo, but there by Masato’s side was his beautiful intelligent girlfriend, Aya Harada.

Contrary to Naoko, Aya has everything: a resolute philosophy on life, goal as a doctor, and pride backed by confidence. Aya’s perfection and existence begins to distress Naoko. She knows she must give up on Masato. But a twist of fate swallows the three of them.
