I'm trying to figure out the name of this manga I read, I remember it starts with the girl moving from Tokyo to a small ocean town, and she sees a boy throw himself into the ocean.

She gets pretty famous as a model and has a traumatic event happen at a festival she attends to, I remember specifically that she keeps saying that the boy she likes is a God? And the manga goes from when they're kids to when they're in high-school.
