HELP ME FIND THIS ONE BL PLEASE

I really need help finding this one bl manga because it’s not the main story but a side story that has nothing to do with the main story I don’t even remember what the main story was either.

So basically there’s two co workers the uke is pretty tall and “buff”? In a way, he’s just not a “stereotypical” uke, and the seme is a cute small person, they met by the seme liking this one cat chracter i think, and I remember a scene before they do it, when the seme tells the uke to wear a cute cat character pajamas and when the seme was done showering he saw the uke in the pj and he got excited.

PLEASE HELO IVE BEEN SEARCHING FOR FOREVER
