I thought Junxi himself even admitted that he never tried to look for or keep in contact with Enxi before he returned to America. He was really sorry and sad about that, but didn't exactly explain why. Perhaps it was because of the pact the family made about not bringing up Enxi's name again to avoid the pain.
Yeah, Enxi's family did have to move around because the bad brother kept incurring debts. What a loser. The mom and Enxi should have just secretly ditched him one day with no forwarding address.
I have three more episodes to watch in this series and frankly, I can't wait for it to be over. I'm liking Won Bin's character more and more while I think Jun Xi is an inconsistent and indecisive wuss.
