It's been months since I played this game but I still feel like trash each time I remember it especially the current 3rd ending with Aiko and gochi possibly falling in love and Aiko been pregnant for goch which is kinda a happy ending but the MC was basically suffering with regret and was having some financial struggles and because regretful for foolishly abandoning his mother and running despite everything she has done for him away cus she had an affair with gochi and caught them.
The MC was majorly at fault for what happened, and his mother and gochi are living their lives happily whereas the MC is living in regret and depression which he deserves for his foolishness. Unlike SOL, this MC is much more stupid and cowardly cus he abandoned the only person that Loved and cared for him.
