There's a few that I looked up; one is Bukiyou na Silent [Awkward Silence]

Sounds like this!
The bl was about two guys who meet playing baseball and they basically grew up together. When they reached high school they decided to quit baseball and the seme applied to a university with no baseball team and the uke wanted to follow him. They also acted like a married couple. Sorry if that was confusing I’m scraping together what I can remember ╮(￣▽￣)╭
