I'm looking for lost shounen-ai, created probably around 2010(older type drawing style). It was about high school/college boy in debts. He was looking for job and he find one, but it turned out that it's something like brothel where employees visit clients' homes to do ya know what. His first and also last client was a middle-aged guy with black hair. Instead of having sex he dressed him up in a cat costume, patted him, cuddled a bit and that was all they did. I remember they met a few more times and became couple, but I don't remember if they had sex. I know the story was funny and sweet. It probably had 3-5 chapters and 1 volume. Does anyone remember? I've been looking for this around 2 years already. I can't find it 😢

Maybe Suteki na Kigawa ga Nakuttemo?
It's sortta cute for a story about debt-motivated prostitution, but not as innocent as you described it though, sex scenes between the couple are in every chapter.

It's it!!!!!!!!!!
Thanks a lot 😁
It's been so long since I read this that I forgot how much sex was in it. Somehow just part with the cat costume stuck in my mind
