i can't stop watching it again and again!! It has a complete dose of everything Love! Sorrow! Happiness! Friendship! and overdose of Comedy and Laughter! Its a series that can make you stick with itself and all time favorite Park Seo Joon He's such a incredible actor I loved him in What's wrong with Secretary Kim and now I love him more...and Kim Shin Hyuk's selfless love is to die for. Friendship like Min Ha Ri and Kim Hye Jin is rare to be found. and at the end the person who actually stole my heart is Kim Shin Hyuk...I wonder how can a person can portray these many emotions making you laugh till your stomach hurts with incredible pranks and expressions...make you feel sad showing how it feels for one sided love...shows what true friendship is always there to protect or play pranks or scare or understand or handle or listen his little sister/best friend/love. Even handling Mr.Ji whenever he got drunk (LOL). Shin Hyuk's a roller coster of every possible emotion. He's like a person 1 in Billions. <3
