Turns out Kill me Heal me was not the first series where I saw Park Seo Joon.

I just realized he was in Dream High 2 as well.

I was like 'I have seen him somewhere else too...' And then I was like ' He's acting exactly like the guy from She was pretty and Kill me Heal me!'

And then I checked him out on Wiki and voila! It is Park Seo Joon!

The weird part is that I had seen Dream High 2 before I watched Kill me Heal me and I never recognised him! My lack of facial recognition skills acting up again! :P
