Don't know if it's supposed to be twisted cute. But sur is relatively light-hearted and happy-go-lucky all along, not in a bad way but not in a good way either.
There's no real afterthought consequences for anything that happened ; Uke lost all his money which lead him to prostitution which lead to him getting raped all because of his happy easy going nature or desperation to others validation.
In general it wasn't romantic, two awkward guys yet extremely different getting together. Seme fall for Uke first and start a stalking spree -taking unconsenting pictures- fallowing him around and stuff that are brushed off quickly.
