This is awesome drama. The story is good. There's many life lessons regarding relationship. The main leads are superb.  Min Ki acting as a cold person was great. He portrayed SeHee in amazing way. Cold SeHee to warm and reluctant SeHee, I found it's really cute. How SeHee became a cry baby in the end because JiHo left him.
Seriously, Minki acting's so great. JiHo's character is also great. She's not typical female lead in korean drama who too strong or too weak. I found her character was so fit, not too strong and not too weak. Sometimes she's strong but in other time she's weak. Her character was so natural. I also like CEO Ma. He's a good friend for SeHee and also good partner for SooJi. Not really like SooJi's character in the beginning, but in the end I like her. I don't really like the other couple HoRang and WonSeok. I found the last couple was too much. HoRang's love was too much unnatural. Not really like that character. Also I found Wonseok was lil bit annoying.
But overall, I found that this drama was so amazing with great casts. It worth to watch it.
