Sakuya Tohno doesn't intentionally isolate herself from others, but it appears as though people simply don't notice her presence. This has led her to develop a sense of inadequacy. She describes herself as unremarkable, akin to air- present but invisible. Despite longing for friendship, building rapport proves challenging as she goes unrecognized. When rumors of the "Thousand-Year Sakura" and its ability to grant wishes circulate, Sakuya seizes the opportunity for a wish to come true. Upon reaching the tree, she discovers four striking young men awaiting her. It is beneath the flourishing cherry blossom of the timeless Sakura that something extraordinary transpires.
