I've read it on here but forgot the name. It is a bout a youn boy (of legal age just looks younger) He lives on a farm and someday a business man (I believe he is a restaurant owner) from far away visits them and their plantage. The boy kinda falls in love with him because the man is handsome and friendly. The man invites him to go visit him sometime and then leaves.
Then the boy decides to go visit the restaurant owner. There he isn't welcome and the man is even kinda mad at him for coming, hence him being nice was just a facade. But later on they kinda fall for each other
It is not a one shot but it is also not a super long story. Maybe someone knows the name of it <3
