_qt's Things

i read this bl manga a long time ago and i can't seem to find it
the uke confesses to a girl he has a crush on at his cafe and asks her on a date, the girl says yes. however, when they got to a hotel on their date - the girl was actually a guy who was crossdressing. i can't remember a lot of details but the crossdresser is the seme. i think the side story was of the seme's high school festival and the uke came.
i also remember one chapter or side chapter where the uke covered his nipples with bandages - please help me find this manga ><

i need help finding a bl manhua that i read some time ago.
basically the main couple are office workers and already in an established relationship. one has blue hair and the other has pink hair. it isn't really a cohesive storyline, it's like those slice of life webtoons where you get random moments of the relationship.
to give even more context, the side couple is a brother of the blue hair guy (he also works at the company) and his love interest is the black hair boy with glasses that happens to be an intern at their company but on the side, he's a singer.
