The plot is the MC is A transmigrator and in one of the arcs he is a brother of the ML.The ML was killed in a car accident and gets reborn.He plans his revenge to the MC because he though the MC betrayed him and sleep with his enemy and one time the MC almost got gangbanged by some hedonistic second generation fox friend of the ML.The MC was miserable and meets the nemesis of the ML,some dog blood and tgen The MC died getting hit by a car.I really want to reread this but I always forgot the tittles of the books I've read.Please welp(;´༎ຶٹ༎ຶ`)
I second that, it's Strategy to Capture that Scum Gong. I see you like self abuse like me, idk if you want reccs but Perfect Destiny and I'm Almost Dead are similar (not just in genre, but the shameless MC vibe and the systems and the dog blood)
