No it's not this but thanks.
Yessss!! Thanks.
I think it's "Don't call me daddy" https://www.mangago.me/read-manga/don_t_call_me_daddy/
And the other manga would be "Don't Call Me Dirty"

This manga about a man who was worried his son was gay and ended up getting together with a man himself. I think there was also another manga about the son and a salaryman.
