Choi Jin-hyeok"s Daniel had a larger role to play. He is looking for a long lost sibling, who may be Mi-young. But the image he portrays is a softer, more vulnerable man than the cocky one we met in the first two episodes. His interest in Mi-young is sparked by her kindness, just like Geon"s was. It"s a nice parallel that both men were attracted by the same quality. He also has a connection to Geon"s family, which will prove interesting when love lines and family lines get crossed. The other second lead, Se-ra, is much less interesting. While she may be genuine in her feelings for Geon, she is very one-dimensional because of her selfishness.
It is clear where our main characters need to grow, and that makes me anticipate their journey. Mi-young needs a backbone - she needs to stand up for herself. Geon needs to learn to have the consideration that Mi-young has for others
