Is it this one? http://www.mangago.me/read-manga/arashi_no_ato/
the color of the hair threw me off because sasaki (the seme) is the one that has lighter hair and wears glasses while the uke has dark hair, and is older too.
nonetheless, i recommend arashi no ato, it is one of my all time favourites. it also tackles about sexuality and love that has no boundaries (๑•ㅂ•)و
oh yeah, the seme is a furniture importer... you must have confused him with maki the architect from punch up.
actually in ANO they did go from bar to bar the first time they met and seme is aware that uke is his type from the beginning but he furiously clamp it down because he never goes for straight guys and the uke is a straight guy that loves his women. uke did try to keep his connection to seme even when seme tries to stay away from him even when he does not understood (that he is actually started to feel attracted to seme).
uke - black haired straight guy. seme - openly gay guy, brown hair, glasses.
Please help me find an older artstyle yaoi manga about an (uke) architect (or was it interior designer?) and his client businessman (seme). The uke is a light haired glasses wearing guy and the seme had dark hair. The uke is a bit uncertain about the relationship whilst the seme is confident.
Sorry I know its not much to go on (because I read this a good couple years ago) but I will be grateful to anyone who tries.
