i read this yaoi manga a while ago and i want to read it again but i forgot the name..

it was like about a guy who is in high school i think, and he was in love with his older brother's friend. he confessed to him and they started dating. P.s: the older brother's friend is the seme and the guy is the uke so i don't keep typing (older brother's friend).

after they started dating with a while, the seme dumped the uke and disappeared.
After 10 years or so, the uke is now working in a company and is getting transferred to a new company, that new company is close to a construction building. the uke went to drink coffee with a friend that is when he saw the seme from 10 years ago, but he wasn't sure its him.
after a while the uke went to the construction building for work, he met the seme there and both of them acted like nothing happened, they decided on a date to meet. on that date they met and the uke invited his self over to the seme's place, the uke was about to make a move but then the seme got a call, but he didnt reply and suddenly told the uke to leave.
sad and desperate, the uke went to that gay bar , he got hooked up by some guy and they walked together. when they were walking out of the bar, the seme saw them and got really mad.

he shook of the uke's hand from that guy and told him that the uke is his boyfriend and the guy backed off. they walked home and then the uke suddenly said " why did you say that, why are you giving me hope" and something like that.

P.s: i know its too long but there is actually more to the story and there are 4 stories in all that is the first one. they are kind of intersecting in away like the 4 couples know each other.. thanks in advance .

Koakuma no Sanctuary?
