Try "Did it work?" or "Bad Friend"
I've read did it work but I'll definitely check out bad friend! ε=ε=(ノ≧∇≦)ノ
Bad friend is slightly different from what you're looking for but I still hope you'll enjoy the read^^

I love this manhwa! Hopefully you love it as much as I did :3
I need more manwhas similar to part-time partner and I can't think straight where the couple has this hateful spite for each other like the top is straight and hates gay people but then suddenly the top becomes super obsessed with the bottom
