I cant remember the title of the yaoi manga I read. The ploy is like this:
The uke found the seme had his heart broken. So they had a one night stand and it turned out that they're very compatible, so the uke can't take the seme out of his mind. But a relationship is a no-go for the uke so he tried to forget the seme.
However, while looking for a job, he got hired at an old restaurant which turned out to be owned by the seme. They started to live together after that.
went to the novel spoiler and apparently ian and ain are the same person (should've figured that out from the names lol)
now i can rest easy and continue reading. i hate reading infedility shit
