It actually makes sense that Angela adopted Minami for that purpose. It's something that could perfectly be a control tactic of a Mexican soap opera villain. It's a way to "make sure" that her "precious child" has a good wife, and if you find similarities it's why maybe Angela decided to adopt Minami with that in mind. This is a way to perpetuate his power over Mike indefinitely, and is one of the reasons he also took a liking to Harmony when they first met, Because she's the kind of "wife material" I've been looking for.mind speaking of things that seem off angela and the whole minami chosen thing (implying minami is actually adopted or at least has multiple sisters) its wierd that angela most resembles minami and not mike it feels like angela should be mikes step mother over his mother and I'll be honest since she's not a romanceable character for mike I feel that she shouldn't really be as involved in things as she is with mike bree somewhat makes sense but even then also the fact she gets involved with brees father so easily just to find out if bree is "wife material" is super strange to unless shes not actually mikes mother and was actually just straight up minamis mother then it would make sense hell minami is probably the closest to resemble angelas personality to only shes more attached to mike and focused on mike
Personally, I'm still missing some pieces for this kind of hypothesis. I haven't played from Bree's perspective yet, nor the developer's other game "My Demonic Romance", which also features Angela, so maybe I'm misjudging the character a bit, but I think the reason Angela talks so casually to her husband about the reason for Minami's adoption is because from her point of view she's not using her as a tool (even though she is), but rather she tried to do her a good deed by adopting her and in a way "ensuring her a future with a good match" like her "golden son" Mike. This being an extremely narcissistic form of "kindness" on her part.
