OK. My curiosity about Woojin's dad was answered (should've seen it coming).
First. We see Andrea is not cut out to become a priest. I know that was a big blow but he did not "technically" kill his father. And now he's off drinking himself away.
Second: His suicide was a long time coming. It was not only the fact the Andrea said he could not forgive him. He took out that bottle and syringe before. Plus he's been slowly killing himself (and hurting his family) with his constant drinking. It was purely his guilt.
Third: Why can't everyone leave Eunha alone. She has her plan and I think this whole thing with both "the boys" knowing where she is will only hurt her too.
Fourth: Poor Yuri. How dare Woojin handle her like that. She is the only sane one in that family.
I so agree with you, I felt the desperation of her character, I felt if I was her I would have ran away a long time ago. Why won't they let her be. . I think I would have jumped off a cliff so nobody could have me. It's a little dramatic but that's what this is, plus people in those situation don't think straight. I say let her die peacefully although if theres a cure please let her be saved. As for woojin, How I love thee but he's out of his mind, how dare he threat her like that when she's the only one that has been in his side. did you see the fear in her eyes. And yes why does woojin, God bless his good looks ;D has to always blame Andrea. The Dad was already a mess, he just needs someone to blame for now.
And why is Andrea wearing his priest outfit even when his working at the construction site? I found that kind of odd, why doesn't he throw on some working clothes? It's like his punishing himself by wearing the priest collar.
I can't believe Woojin 2, who's completely batty. The only person that matters to him besides his oh-poor-me self is Andrea!! He treats his little sister like a piece of cr-p (in that scene where he took that letter from her--does he think everything in this world should belong to him?) and makes her lie for him, bullies and pushes the dying Eunha around (I mean, come on!!!), all because of his obsession with Andrea. Let's face it, WJ was screwed up before he ever knew an Andrea existed. He just found a convenient object on which to focus his paranoia and self-pity. What a mess he is.
The father was also a drug addict. I've seen that "kit" on his desk before--needles, bottles, and tourniquet. So sure, it's Andrea's fault for not INSTANTLY forgiving the guy right after he confesses he killed his father. Jeez, give him a couple of days to process it at least. "I killed your father and made your mother throw you away like a used tissue. Forgive me, please?" "What?? O my god, NO!" "Oh, I can't live another moment with this guilt I've carried for 30 years, and therefore I'm going to kill myself immediately." Yeah, makes sense.
