 If you liked Kimi to, Nami ni Noretara |  ...then you might like Deji Meets Girl |
Similarities - Both MCs live by the shore/sea - Both MCs are in their teen (in beginning) - Both MCs escape reality (try to at least) - Both MCs experience supernatural visuals of being submerged in water with fish surrounding them Differences - Ride your wave is sad/tragic VS deji is lighthearted and dramatic at times - RYW is about surfing VS deji is about small time family inn and a runaway celebrity
