He was such a great character and the actor played it to the perfection. Clumsy yet thoughtful , Super Rich yet hardworking and maintaining loyalty....I was really hoping he would end up with Jung Sun not gonna lie . He comforted her and always looked back at the husband ( who was ignorant) before doing anything for the FL , never crossing a senior-subordinate boundary.....love him . 

I love him more here, because I watched this after "Crash Course in Romance" , so if you know....you know.... 👁️ 

I loved the other two second couples as well....Mina's husband was so what of a realistic character. 

Which character did you like the most ????
