I understand that the dev wants to make a cuck/NTR game but, since he/she's focusing on the story here, I just want to point out that it makes no sense at all. You have the sweetest girl hanging out with a bully and although she says there are more to him we see no redeeming qualities, just a bully. I found this story element really off putting and it pulled me out of the whole plot, especially when the guy started talking about the MC being a cuck and she said that he's being weird TODAY. Apart of the fact that this is the shittiest way to defend your friend it makes no sense that she's surprized that the known bully is bullying his known victim.
