Try Arts Manz if you havent read it. I consider him second ML because we see the first guy first and it seemed like the author was pushing him with the MC for most of it
Tysm! Ima check it out

I love when the final male lead is a bit unexpected but it's so rare TT, I also want recommendations
Tyy, and same its one of my fav tropes but it never happens lol
Recs for BL where MC ends up with second ML??
