Stay by My Side

Enemies to lovers is the main similarity
I don’t really have many reasons but when I was watching STAY BY MY SIDE I kept remembering BAD BUDDY and how they got off first to how they grew into the most adorable couple

Both are from the same universe/world
The main character in SBMS had a cameo in AR and it's special episode.
Both dramas are BL.
