While watching this show i kept thinking about come and hug me to me both felt the same ,the lead male are very a like and their back story is similar and if you look at the posters even they look the same .
I must add that i loved both shows very much but i think i loved come and hug me tiny bit more .

Same vibe , cold boss that falls in love with his employee,i would say that "What's Wrong with Secretary Kim?" Is better but i enjoyed both shows .
