Help Me Identify This BL Manga

All I can remember about this BL is that I found it as a oneshot in between other stories (like an anthology). I can only recall that the seme is white haired (or light-coloured. I can't tell when it's in a black and white scale), wear's glasses, is probably working 'cause I remember him being in a suit once and uke is black-haired(or dark-haired) annnndd, the kicker is that this is an incestual relationship (tbh, I can't recall if they're step-brothers, or cousins. Do with that what you will).

There is one scene where I vaguely remember going:

Uke was reminiscing about his love for the seme, while aforementioned seme is sleeping on the couch (exhausted from work idk). He approached the couch and sat next to the seme, close enough to the seme's face. I don't remember the next part, but the seme unconsciously grabbed the uke's head and kissed him, while in his sleep. Seme didn't realise it until he woke up from it(ig the uke's noises of surprise or something). He apologised and stuff but that's the gist of it.

Anyway, let me know if you know where this is from, thank you. I've been thinking about it for WEEKS and I need to satisfy my curiousity.
