Can someone recommend more manhwa like this were the seme is so desperate and loser

:))

Ho I got you! One of my favorites is A man who gives it all. It’s a love triangle though.also kinda Leaves dancing in the melody (but the top is just a hot crybaby)

Alternative name for the second suggestion?

Try to look up “Ipsae's Leaf in Haneum's Breeze”. It’s the name on this website. But the original name is Leaves dancing in the melody

Ohh is it the one with the same artist for YTC?

Yep it’s even better than YTC. I heard it’s the same artist but different writer of the story.
