Dude, Saegye's own father abused him his whole life too????? Only difference is that Saegye was a dare and Jinsol was a false????? Dude had no fucking excuses, his sister was safe and he could have moved out, or he could have force kissed Saegye and ran away (like he did with Han) he didn't have to play him like that
How could they possibly move out? They didn't have money, their mother wouldn't help, and since their father is a truth he could easily go to the police and tell them all that there is about Jinsol being a false. Even when gis sister went to their mother, he couldn't forgive his father (I think I must add that then again he was abused even after his sister was gone) I mean they really couldn't move out.
But about the part that Jinsol played Saegye, well you're right and that's why I wrote I wouldn't do the exact same thing at the end of my comment. But we're not done with these flashbacks. Maybe he had a reason for that too which I don't think would satisfy you or justify him. But it's necessary for us to know why he did that (at least for me) Even if we can't accept his reasons.
Moved into his mom's house, his sister did, she was more than happy to take his sister back in
Am I the only one who can understand him? I mean I get why he would do that. Imagine being abused your whole life by your ownfuckinfather (his sister too) Of course you'll loose your sanity at some point and won't be able to distinguish good and bad from each other. I'm not saying what he did was ok I'm just saying I didn't expect anything else from someone like him. Put yourself in his shoes and you'll get what I mean. Btw in these flashback you can clearly see that he..well I won't say fell in love but at least had something for that dare guy whose name I don't remember right now (sorry) And he feels sorry and deep down he knows that he's the one at fualt. If you have read the spoilers, you must know that dare guy will find Jinsol's dairy and it's only then that he tries to understand him a bit (he even goes to Jinsol's house)
So with all of this being said, I think I don't consider him as a scum or I won't tell you if I were him, I wouldn't do the same (well not exactly the same but oh well..)
