Pig's feed

I'm looking for manhua I read some time ago but I don't remember the tittle ;___; Art style was realy good, top was a 30+ guy with glasses and white hair and bottom was college guy with black hair but more well built than the top, it was nsfw. Story was about how they both understand their relationship??? The top was very hesitant about "love" I think. I have memory of a gold fish but I remember it was super good and I want to reread it ;___;
