A boy gets one chance to save the girl he loves from a future that's already written. What makes this work is that he actually earns her, and then has to earn her all over again knowing what he knows. Two episodes that understand the cruelty of time travel isn't the paradox, it's having to watch someone you've already lost fall in love with you for the first time.

Koutarou has decided to confess to Kaho, a girl who seems out of reach, once summer vacation begins. The night before he plans to do it, a run-in with a strange girl sends him into the future. There he learns that Kaho has become his girlfriend, but she has also died in an accident. He returns to his own time with one goal: stop whatever is coming. Now he moves through his summer with purpose, jumping between past and future and using what he knows of later events to rewrite a fate he has already seen. Koutarou splits his time between pursuing the girl he loves and trying to save her, in a two-episode OVA that blends romance, comedy, drama and time travel.
