they’re both fucked in the head and don’t deserve a happy ending like how can two people be in a healthy relationship after this???
Of course he isn't innocent,nobody is. The stuff he did were bad but they weren't evil and definitely not crimes.a lot of factors led to sungho being fucked up and dohyun's manipulation is one of them,he still didn't deserve any of this torture,his life sucked even before this,you could say that his state of life was his punishment.
even after reading this manhwa three times i always love it just as much as when i read it for the first time :(
