From what i remember it was a mix of him being a drug addict (so not really in a sane state of mind bcs the drugs they used is a strong one) and Brandon using his position and power to have "sex" with him. He was initially just a subordinate fighting other gangsters till the old man got sexualy interested(obsessed) in him because he was strong and attractive. I don't remember exactly if some of it was actually done (before Mathew even got involved with him) with consent but there was a clear power imbalance so it's not too far from being considered SA
Revenge not really, at least not in a satisfactory way but I guess he ended in prison(?) or something happened to his business like a scandal of the trafficking of hard drugs.
Sorry i can't remember clearly the plot since a lot of time passed from the start to end, but It's more hinted that they had a ""relationship"" that jin is not really that fond of.
If you are considering to read it or not it depends on what you consider to be too much for you. All the sex scenes are mainly between the main pair and yes there are some that can be considered questionable even between them. There are some scenes with attempted sa on both jin and Mathew and there is an usage of drugs by the characters (main and background)
If somebody else have something to correct because I'm going with my memory rn
So i read the comment and apparently the MC is SA'd by a "Brandon".
Anyome can give me the details of the situations ? Was MC drugged ? How did he end up in that situation ? Did it happen many times or one extended time ? And did they get revenge on Bramdon ?
