After reading your description I thought of this one, but I'm not too sure

Too bad it's not.... the manga I'm searching is not collection of oneshots and they still haven't had sex or confessed each other feelings.... they went to seme's house after drinking (if I remember correctly) and the seme told the uke that the uke is the first he brought into the house because he doesn't like people come into his privacy (hinting that he's interested in the uke), when they decided to sleep (sleep side by side, not sleep = sex) the uke was thinking that did the seme let the uke spent the night in his house mean something deeper like he (seme) likes him (uke)...
There's this yaoi manga... it only has one chapter (still ongoing). It has beautiful art, and the only thing i could remember is the uke somehow spent the night at the seme's house. And the seme said that he won't take anyone to his house, so it's like the one whom he let into his house is the one whom he loves (or something like that). Both seme and the uke are working adult in suit.... now, anyone knows this manga?
