it was a villainess manga where the mc had curly drill-like hair and she was close with her butler, who i think was the same age as her? takes place in an academy setting and she tries to act like a proper villainess but just ends up unintentionally being nice to the OG heroine.
Hi! have you read these? Not sure if they’re the one you’re looking for but they’re still worth the read

I found these in my list under "butler", "servant" and similar context
no drills but butler MMC:
Akuyaku Reijou no Shitsuji-sama Hametsu
It seems My Lady is the Villainess with Only a Bad End, so I'm Thinking of Saving Her
I Raised an Obsessive Servant / My Ray of Hope
no drills but butler supporting Ch / ML:

wait maybe im missing something but arent gunwoo and mc relatives/distant relatives?? idk im only like 40 chaps in but earlier on i think they introduced gunwoo as mc's distant relative...
they are not distant relatives (or even related) they are just called that because eon was picked up from winning the tournament and made into the eon family successor because there were no other candidates. the eons are the maternal side of haewon's clan. so basically her moms clan. they have no blood relation.
gunwoo* not eon sorry. gunwoo was basically adopted into the eon side of the family.
ohh, thank you for explaining!
