https://www.mangago.zone/read-manga/bj_alex/ was it this one ?
No,i think it's a shounen ai or something cause i think it doesn't have any s*x scene
I'm kinda wrong in the buying gifts part. I think the uke(main couple) is always calling that guy(seme in 2nd couple)sunbae.So this sunbae is always treating and always asking him to eat with him and always talk to him first being so kind and friendly etc to the uke so the uke's friend got so suspicious about him saying something feels off about that sunbae and it irritates him but they found out that the sunbae is just talking to the uke and acting friendly when that friend of his is with him but his friend always hated that sunbae's gut etc he doesn't really like him cause he looks like fake when he's smiling(which is kinda true hahaha cause that sunbae is always coming to talk to the uke just to be with the uke's friend)
It doesn't have a s*x scene but i think you'll know who's the top and bot just by looking at them(but i don't even remember their faces lmao)
Ugly mutt lmao HAHAHAHA and why do i feel deja vu?? I remembered i reading something like that scene where the seme(in the second couple) is always buying gifts for the uke(1st couple) but he's really not attracted to that uke but to his friend but i think it's not the same case as heesung i just suddenly felts a deja vu Lmao
Anyway don't ask me the title i dont know either(i freaking forgot i only remember that they were the 2nd cp)if anyone knows please tell and you can also suggest something like this since its so hilarious
