Miko from osora

Simplest explanation I can give so I don't spoil Osora.
This is Miko.
Miko's boyfriend is named Apollo.
Apollo is 29 in the time that he's known.
Miko is only 21.
They've been dating for 6 years.
There's a problem, do some math.
Apollo is a CP (Child Predator).
Miko was 15 and Apollo was 23.
Miko was groomed by him into a relationship.
Apollo abuses him, cracks him, and then is kind to him to keep them in a relationship.
Apollo also isolates him and manipulates.
Miko still loves him though, at least he thinks he does.
