Marriage, not dating is addicting for me because the story interesting and the character so funny. It's like Romance, comedy. I watched it few times. not getting bored.

Strong Woman Do Bong Soon (I'm not watch it yet, but i plan to watch it. Interesting just from trailer and because Hyung Sik play main role there)

Shopping King Louis, this drama funny because the rich guy not always smart. he dont know anything about the world but he reaaly smart to choose a good thing from online shop
