Help me find this BL pls

I'm looking for a japanese bl manga. I do not remember much. Just that most of the setting took place in the top and bottom's usual gay bar. I remember that the top was being forced into marriage otherwise his dad or grandad would disinherit him. And the bottom, originally a top( neither wanted to bottom so he ended up saying yes to bottoming because he actually liked the top)said they should try it out and see if they could work together as a couple so the top would not marry a random person. That' s all i remember. The top would usually wear like a suit or vest and the bottom would wear a shirt and jeans. They both had sort of long hair but not Down their backs. I remember that it's about 5-7 chapters long.
Ty!!
