I gave it up at episode 10 and have not returned. As I read your review, I am glad I didn't. I was also hooked during the first episodes mainly because I liked Lee Jong Suk's acting, but as we all know, that is not enough.
I don't know his name, but it is the second lead from The Prime Minister and I (I disliked him a lot) who is Enrique in Flower Boy Next Door (I so loved him there).
Do not watch this drama while hungry! I watched most of the episodes at night and I was like a ghost in the kitchen looking for something to eat. I must say I really love this drama. This is a drama with an awesome male lead and the dinamic within the friend group is amazing. A show about friendship, love and of course...Food.
