How to write an SA scene in the perspective of the perpetrator?
I’m writing a story in the perspective of a very repressed gay man in the 40s who is ‘friends’ with a black man who he somewhat fetishes and views as less black. (if that helps with anything). he ends up falling in love with this man but ruining his reputation with rumours and such. The friend HATES the protag very much because of the rumours and avoids him in general, however they work together with a mutual friend to buy contraband to sell in the college they attend.
While the protag and friend are alone, the protag confesses and the friend is disgusted. Protag basically comes onto him and begins aggressively kissing him and the friend shoves him off after punching him in the head, cusses him out, and leaves.
The protag is very delusional and is constantly shocked that his friend doesnt reciprocate his feelings.
The thing is I‘ve Never written a scene like this before and I have no idea how to write it in the perspective of someone so terrible. Any help is appreciated! Also if I worded anything of this oddly please tell me so I can edit it.
