How to Hate You

It has the same lead actress and overall just a simple drama to watch that has a pretty interesting plot.

Korean mini set at university, love triangle included. Short and cute with nice chemistry. Stereotypical to the very end, but nicely told.
If you're looking for a better version of Our Love Triangle, try How to Hate you instead.

male chases female first
high school/college
FL likes another person at first
pure and innocent love

its pretty similar to me because of the cold bad boy and a nice girl, and the vibes are pretty similar
