Around episode 5 I was liking this series a lot, but I sensed that things would end badly. I read some spoiler reviews and I was dismayed to find ppl saying we should stop at ep 9; the rest went downhil badly. I begrudgingly continued with the series. It starred Son Ye-Jin from Crash landing on you and the 2nd male lead from While you were sleeping. They even mentioned that series when Jin-ah and Jun-hui 1st reunited. I think the series was supposed to give us the varying emotions of love; the butterflies in your tummy, the joy and laughter. The fear that it will end and the heartache when it does.
Most reviewers blamed Jin-ah for ruining the relationship and I was angry at her selfishness around episode 13. Then I realized all she'd been through.
Her family and that atrocious mother; her job and back-stabbing co-workers. Even Jun-hui's sister was horrible for a time. Still, she loved Jun-hui enough to stay with him. He wanted her to run away to America and then HE decided to leave by himself, when she would'nt go. This was his fault, because although she wanted her independence, she always was happy to be with him. Jun-hui showed his younger age, by being insecure and running. She let him go because she thought it was best for him. That's why she wept in her apt and refused to see him the night he left.
When he was packing and heard her message again, expressing her love, he realized that her love was displayed for him throughout the series. That is why he asked for forgiveness. In love and life our rash decisions usually get us in trouble. It is patience that Jun-jui needed to use for Jin-ah.
