Time teaches me to love
My Secret Romance- This one has a slight love triangle, nothing major tho.
What's Wrong with Secretary Kim? - Also very slight love triangle, nothing that will compromise the relationship.
King the Land
High End Crush
Business Proposal- Slight love triangle, the other guy was jealous and recognized his feelings too late. nothing major here.
Girlfriend- Kind of??? We have an annoying 2FL and an annoying ex. But I don't think I would put this in a love triangle category.
Love Me Like I Do- Yes, but it's small and short. The other guy is barely even shown in the show.
The majority of these have little to no love triangles. If it does have one it's either short lived or doesn't really matter in the story. (doesn't give any 2ML syndrome or heartache)
