Yes but remember, when she took him off the list, the director immediately spotted it and asked "Why isn't he on the list?" This means the criteria for the list had been pre-decided.

Definitely the most narcissistic scumbag! On the other hand, because of the actor playing him, he is also adorable at the same time.

Have you watched Misaeng?

He had a secondary role there, and it was mostly goofball comedy. He was meant to be awkward. Let's say the writer/director made use of what he is everywhere, to make it suit the role. Very clever of them. (The drama was awesome, though).
Yes, he was also okay in Oh My Venus. Interesting role. Nowadays he tends to play only cool chaebols.

It would be wonderful if it were Lee Sung Min and Nam Da Reum.

Yes. I wonder how on earth he keeps getting leading roles. The only time he was decent was in Five Children, playing the arrogant and narcissistic golfer. But every single role in that drama was so well-written, and the director was very good too, so everyone was able to give their best.
