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
i personally like both so you can totally check it out

both the dramas have a NCT member as the Male Lead.
both are male chasing female first trope.
it has a secondary couple.

the male leads of both the drama are idols- both of them from SM's boy group NCT.
both are web dramas for a short binge.
little cliche but overall good.
highly recommended if you're a NCTzen or want to become one!
