Temptation of an Angel Episode 15

The beginning of the end.

So Hyun Woo is revealing himself little by little to make Ah Ran and Joo Seung restless, I think it's a good move to play mind games with them even the marriage talks almost made me feel bad for Ah Ran, she will be betrayed by the only person she loved but then I remember what happened at the beginning and how she even betrayed Joo Seung, I feel good.
On another note, I understand Joo Seung's feelings of inferiority, I mean he always felt that Hyun Woo's taking his mother and living a normal life while he was dumped by her but I can't possibly understand participating in killing his older brother: that's sick!
