He didn't want the child to suffer with debt as well. If the mc committed suicide by himself the child would have to live an even more sufferable life. I'm not saying it's okay to commit murder-suicide but MC was not exposed to a normal life. Goodness knows what would happen to the little boy if he was given the responsibility of paying ₩180 million..
Also he was being sexually assaulted..? "could have cried instead?" Do you lack comprehension skills? If you we're sexually assaulted you wouldn't do anything to defend yourself?
Don't know what type of sunshine and rainbow world you're exposed to but the real world ain't like that. But no one is perfect. If you don't like the manhwa, that's okay, but there are real people in the world that are in these situations and people like you, who blame and villianize victims, are the reason why this world is so shi***. Bc you guys are the same people to condone the actions of the actual predators..
