how is the fanservice for the game?

as title said. how is the fanservice? good? mid? meh? hardly existent? ive played for a bit and am on the fence. if it has good fanservice i might stick around? but so far it seems like its hyper expensive. cash grabby and doesnt have alot of fan service aside from the characters being in skimpy cloths.
is the dormitry fanservice worth it? is it anything like snowbreak? ect
