I've been searching this forever

I forgot the title. Does anyone know bl Manga uke is an office worker and the seme is the boss. Uke likes the boss. They are quite close until it seems like the uke has stayed overnight and woke up him up, I forgot how the story was. It seems like their first kiss is on the office stairs. Sorry if there is a wrong word or sentence, I use Google Translate and I am also bad in explaining.
