Sun Oh, should have been the choice.
Sun Oh & Jojo are easing around each other, they have total chemistry (Their kiss was before love) and their both share their pain (being each other's therapist)...They were so happy together. I feel that their love heals each other and that they can't find it elsewhere.
Sun-Oh always loves Jojo even when he was in pain. It feels really wrong to have it any other way.
Hye Yeong, is very dull with Jojo. They don't have chemistry. She doesn't seem to be as happy as when she was with Sun-Oh. She doesn't share any intimate pain in her past with him.
What's the heck with Hay-Yeong when Sun-Oh got his phone taken away? Why couldn't he just told Jojo that Sun-Oh's parents locked him up? I was so annoy... and feel like Hye-Yeong has a lot to do with their break-up.
