if its abo then this is what i was thinking of, the 'friend' has red/brownish hair but no piercings sadly,,, http://www.mangago.zone/read-manga/how_to_chase_an_alpha/
Awww but its not it. The friend is kinda creepy and obsessed with the seme. He wanna fck the seme(his friend) so bad to the point he fcked all guys who looked and has the same build with the seme and the last chapter I've read was seeing the clothes splattered on the floor and wasn't sure if he did fck the seme cuz I didn't get the chance to read the next chap. Ugh kinda frustrating lol
I kinda read it long probably last year but i drop it lol. I only remember being anxious if his friend (seme's friend) fucked him. I only remember that scene. The ml (uke) and the seme got into an argument the seme's friend is somewhat obsessed with him like fcking someone who liked the seme but the ml (seme) didn't know. So he got drunk and called that friend the last chapter I've read was there's clothes scattered around and there's a guy lying beside that friend who has the same earrings as seme but I didn't got the chance to know if there's something happened btw them cuz I forgot the title lol.
