I just watched this movie and really.. Seo In Guk's acting was just a FLAWLESS AWESOMENESS! I know Lee Jong Suk was seriously amazing, too - but his acting was steady and the role Woo Sang had no considerable difference from his other ones. Seo In Guk left a good impression on me since Master's Sun. I totally forgot he's actually a singer.. KYAAAA! He's damn amazing at singing and now shows how talented he is through his great acting. A GENIUS, REALLY~
And I won't forget to say that, Yuri's acting skill improved ^^ But I think it would be better if an actress had got this role. I'm thinking of Kim Ji Won because her smile is stunning. But of course, Yuri did a great job!
*claps claps*

Anyway, I love this duo so much. The ending was fine to me. I love how the PD didn't let Jung Eun make any particular choice between these two hotties! Both Woo Sang and Won Il were good guys <33 LOVE 'EM SOOOOOOOOOO BAAAAAAAAAAAAAAAD <3
