Bl manga title

Heyy, I'm looking for a bl manga I read a few years ago but I can't remember the name. It's really a Japanese manga, not a webtoon, with like b&w pages. It's only a few chapters long, the main character is a blonde guy who's rather thin. He always wears a white surgical mask cause he is very sensitive to smells (I think). The art is just gorgeouuus
(It's not ten count in case you'd think of this one)
Does this ring a bell with anyone? Thank youuu ^^
