I like that scenario, maybe OGFL is working with the person who trapped her in the mansion. I’m thinking that even though the easy/normal mode with OGFL was supposedly a happy end, this hard mode gets into the real stuff like you said that everyone secretly loves Sera but settles for OGFL. I remember when she first came to the mansion, the person who trapped her said that when she finds out who trapped her, the person hopes she picks them. （￣へ￣）
I read the spoiler, the gamemaster is OG sera. The OGFL jealous over Sera who loved by the mens. She's just a delusional chick who wanted all the mens attention.
?
Theory is that the actual gamemaster is the ogfl and she's trying to set sera up with the guys cus she dislikes them... More like dislike them in the sense that they are only with her as a 'replacement' like for eg, felix only likes her to make sera jealous, you can tell how shallow his feelings were. So it's just basically about her body and sera's interest.
