Thanks for the Summary Yuko
Okay I do kinda feel bad for AP Huh, I mean he really like Joo Yung especially to do all the crap he did for the guy when he got disowned by his family. And now he got smashed in the head with a brick because he was gay. The dude must have some seriously bad karma. Well at least Inho found you before you bleed to death, maybe there is hope for you yet.
Joo Yung you poor idiotic ba****d, I mean your bf is calling you and crying because you dumped him, and you ignore him, get wasted, and make a fool of yourself in public. I mean dude the guy probably honest to god loved you to do all of this, rent an apartment for you, steal money and got blackmailed because of it. Dude you should be like eternally grateful you got someone who liked you enough to do all of these things for you.
At the moment Joo looks pretty bad, but if you remember the beginning of the series, AP was kind of a jerk to Joo. Now that we know more we can blame AP's poor attitude on his depression about his mom disowning him and his stress over Jung knowing that AP stole the money, but he never really told Joo that.
AP used to bitch at him every-other chapter so Joo wised up ad realized it wasn't worth the abuse. If AP had told Joo or apologized maybe Joo would return his calls. Yes Joo "owes" AP for taking care of him by getting the suite, apartment, and daring to take the risk of engaging in a socially taboo relationship, but that doesn't change the rude behavior.
