one of ML's friend who appeared @ 42:01 seems like Yeon Woo from 'Love catcher 2', I'm not sure thou anyway, really liked the first ep and can't wait for the 2nd ep.
Glad I gave this another chance coz ep 1 wasn't impressive for me but all the comments here were positive and now I'm suffering from serious secondary couple syndrome.

I didn't know that I could feel so hooked while watching anything like this.
