The four male actors were just AWSSSOME love their acting BUUUTT the reason I gave an 8 on acting was due to Kim Ha Neul's childish act..(omg even the youngest of the 4 women acted mature than her).. I mean I got to the point where I just skip skip skip through her parts!... I love her in other movies/dramas but in this one NOOOO she got a 5 from me... Other 3 female actresses were awsome too.. The guys did a really good job, acting from them felt so natural and their relationship was great, you can actually feel their pain, laughter when they support each other through hard time!!..GIVE IT A GO LIKE I DID!!... I love Im Me Ah Ri and Choi Yoon's relationship!..
