Help please

So I’m looking for this bl manga (it probably was a manga not a webtoon) and the only thing I remember is that the couple had a child (probably seme or uke’s?) and in the end of the manga the child was all grown up and he married a woman and people were like “wow a manga where all characters aren’t gay finally” lmao. That last scene was really wholesome as far as I remember tho... Please help if you remember sth like this ┗( T﹏T )┛
