The World Is Invisible From You

During the spring of his senior year in high school, Keito tours a nearby college campus and has his heart stolen by the acting performance of Yukichika when his film club's shooting a scene in the middle of falling cherry tree petals...
Yukichika was in the middle of acting out the scene, but since Keito walked right into it, they stopped filming and started searching for a different location.
When Keito asks who he is, he says, "I'm just a creator."
It turns out this chance encounter is what changes Keito's destiny and begins a "love story" in the "world" he lives in...
