I think it is a black and white manga
the bottom works as a male prostitue he was really pretty
the top is younger like 12 or something and he fell for the bottom at first sight and wants to be with him
the bottom only says you can come back when you are older and when you have money
but the top comes often to meet him and bring foods with him and the years went like this
the bottom is afraid of the club manager or someone who forced him into this job. And the bottom slept with one person who thinks that the bottom became his wife and kidnaps the bottom and imprison him in a hotel for one month having sex everyday and him going for work locking the bottom inside and the tops find him(this happen when the top was like 18-20 )and saves him
after that his abuser(who put him to this work) also gives trouble the top and his father (the father was not shown at the first of the manhwa but at the end he comes and let the top and bottom escapes to a scheduled mountain with a house
