A confession that should be the happy ending becomes the moment everything breaks. Ken gets caught between the woman he promised himself to and the one who makes him feel alive, and there's no choice that doesn't hurt someone. The OVA refuses to pretend this is about who deserves him more, it's about how love dies the moment you stop choosing it, every single day.
Hotaru finally confesses her love to Ken, and the two become a happy couple. Their happiness lasts until one summer, when Ken gets to know Tomoe, Hotaru's best friend, who has a charm all her own. Ken now faces two paths: stay with Hotaru or be with Tomoe. If he cannot choose, he will lose them both. This three-episode OVA is a romantic drama built around that love triangle.
