Hi! Please help me remember the name)

It is about a shallow guy (i think his name was Bo, but maybe not) who met another guy in a gay bar, spent a night with him. in the morning that guy told Bo that this was his first and last time before marriage and left. It turned out that he was very rich and had to marry a woman his family chose for him.
That's all I remember...
Thanks in advance!))

Is it Shinshi to Norainu?
