You've stated it, she's obsessed so most likely she has feelings for her and she's taking potential suitors away from her since she can't express her feeling for her so she results to ruining her life by taking e.g. Her fiancé
Actually that can be a possibility that she like Mayumi. Nice analysis ...
Coz I have always been thinking from the very start that mayumi’s snake friend is just plain jealous of her & don’t want Mayumi to be happy.
I’m gonna b*tch slap someone...Why is she so obsessed with mayumi?...that b*tch better not come after Mayumi..I swear I’m gonna cut her...
Actually the only good outcome on what that snake girl did is that Mayumi didn’t end up with that stupid, dumb, useless, cheating bastard ex-fiancé.
