Hyung's manga / #Cheating(2)

What in the mf-ing cancer-as-a-plot-device was this. I've never been madder in my life? (Actually, I take that back. I've read that one manga about the regressor whose fiance cheats on her with her sister.) The characters are sad and pathetic because their situations suck/they don't wanna take responsibility for their actions/insert sad emo reason here. Translations go downhill part way through. Where's my refund bro :(
