Maybe another female competitor could be introduced, like the protagonist's close friend or another junior. 美亜 is currently stuck in a cycle of self-deprecation, helping her get out of this slump and 亮 is the protagonist's job right ? But whether they can smoothly transition into a romantic relationship afterward is still up in the air.
If 美亜 keeps seeking attention by seducing the protagonist's lover, it might be hard for them to develop a romantic relationship. It would be great if she could realize in the punishment game that she has a chance to become the protagonist's lover and actually start pursuing her. If that doesn't happen, maybe a female competitor could give her a little push.Because of 美亜's reckless behavior, her image is a bit tarnished right now. It would be great if she could make up for it by showing her passion while actively pursuing the protagonist.Of course, this is just my personal opinion
