The seme was asked to be a cameraman reliever for a day for a gay porn shooting. He finds out that the actor is a high school schoolmate and the actor doesn't know he's going to be filmed so the seme helped him out to escape. The actor who is the uke was a popular handsome guy in their high school. He was scammed by his boyfriend and didn't know he will be used for pornography. The uke has low self-confidence and thinks nobody's going to love him but the seme thinks otherwise and told him he's lovable and they had sex and became a couple later on and the uke lived in the seme's apartment.

I can't remember the title but it's a very lovely manga. I hope someone can identify it so I can read it again. Thank you very much in advance!
