The Crows marriage and Souteigai no Sweet Marriage kinda fit, maybe?
The crows marriage was originally about an arranged marriage, but to bottom’s sister and souteigai is about 2 guys in a pretend marriage to avoid people trying to hook them up with others.

Looking for something similar to Muri Marriage or even Marriage of a Miko! those arranged marriage because of tradition, where they eventually fall in love... better yet if one of them already fell for the other first (๑•ㅂ•)و✧
