I don't know why jojo did it with sun oh. She literally had no reason to dump him.. Honestly I was so upset to see that. Okay! Hye yeong was a good and kind guy but sun oh deserved better.. Also I don't understand the character of Kim jojo. she was happy with sun oh, what happened to her mindset after their accident, only god knows... Suh oh begged her for the reason, why she's leaving him. But she gave no explanation..... That was so heart breaking... But truly if you wanna cry. Try this drama... Song kang's acting was just awesome..
