Took a liking to Alejandro. She strikes me as not a yandere but as a high level "Justin Bieber fangirl" type.
I generally don't like this theme when it's used in games for the main LI because it flattens the relationship (we as mc don't have to do anything because we are unconditionally loved without any kind of effort, contribution on our part), but here (probably because we are looking at it both as a player and mc from the side) it was really well done - it was fun and entertaining so congrats are in order.
As we were extremely quickly shown the existence of the fangirl theme and the information (rumor) that she is after the breakup, I can see a lot of potential for an interesting transformation of this character into a "bad ass girl with a broken heart" who gets tough to prevent the world from hurting her again.
Saw that she was placed in the "Unlikely" category - a pity, nevertheless I am interested in how her story will turn out.
