The Villainess's Guide to (Not) Falling in Love (Manga) 01

It is pretty good, but she is so concerned with not being doomed when it is so easy??? 6 months until the heroine appears, so time to study and just not be a bitch to her when she arrives. Like... that's all that needs to happen.

On another note, is the brother a potential love interest because oh my god. I'm seriously wondering if this character was adopted into the family hahahaha and hoping because he is honestly the best.
