Omg. I just checked and i think (95% sure?) It's this one! * - * (i remember curtains on their beds and i've the feeling that i've read this story before) My memory was really confused so "the guy touched himself while he was thinking of the other and maybe the other one saw or heard him" part was just me trying to guess ...but it seems i was totally wrong. haha. Thank you!
If anyone has another suggestion, I'll take it too.
Haha well if it’s the one then I’m glad you found it (๑•ㅂ•)و✧
Hey, It's been a while (years?) so I'm sorry if the description i make doesn't help you to help me..
I'm looking for a manga (yaoi) where there were 2 guys who were sleeping in one room on bunk beds. (highschool or uni-students?) And if i remember well one of them loved the other one. I think they were bestfriends or something. I'm confused (i read it long time ago) but i think the guy touched himself while he was thinking of the other and maybe the other one saw or heard him...? I don't know but the most important thing is at the end they end up together. Thanks for your answer or recommendation. I'm quite desesperate, haha. ╥﹏╥
