Does anyone know the title of the yaoi /shounen-ai manga where:-

After uke’s parents died, uke's father's friend (seme) chose to take care of him, and uke' fell in love with seme and constantly tried to act innocent and pure in front of seme, as well as always try to seduce seme. At first, seme only thought of him as a son, but after some time, seme also fell for uke

I can't remember specific titles but I have seen multiple stories with that type of story. Do you have any other details?

Even minor details help, if there is an element that you think 'might' of been in it also list that (do note if anything you list is not a definite)

Examples of helpful information:

• Was the Uke still a minor when the relationship started ( under 18).
• How long ago did you read it? (ex 1+ year, 3+ year)
• Did you read the entire thing or just part of it?
• How many chapters? (estimates are fine)
• Black & White? Color?
• Manga/manhua/manhwa?
• appearance of charaters (hair color etc)
