First story: dude says friend is disgusting for telling him he loves him but actually he loves him too but hes just scared. Punish himself by sleeping with fucked up people. Childhood friend knows it and saves him lol.
Second story: dude who sleeps around with girls goes to live in the countryside. Ends up being way too good friends with his neighbor. While both are kinda drunk they sleep together. So he goes back to the city bcause hes like wtf did i just do. Understands that he loves him so goes back and they happy ever after.
