1st: This drama has amazing soundtracks. Gummy, Hyorin [SISTAR], Yoon Mi Rae! They collect every amazing voice in South Korea. Not just music and voices, lyrics are amazing too. 2nd: Promo photos, posters are awesome too. I don't know who is the photographer or who's idea is this concept but it fit perfectly for the show and for the actor/actress. The moment I see the teaser I wanna watch this drama. This drama's staff know how to market a tv show for sure. 3rd: Awesome cast! Gong Hyojin is really pretty even though those dark circles and messy hair. I regret that I didn't know her before. Her acting is amazing. I'm gonna watch every job she has done. So Ji Sub usually had "cool" roles. "Being quite" , "beating people", "living a miserable life" those are usually basic of his roles; till now. He's one sassy boss with a miysterious past. He's super happy according to his previous roles. This character, Joo Won is sassy but funny at the same time. The way he changes his expressions made laugh everytime. 4th: Can I join the cast just for dresses!? I'm a girl but I totally wear Ji Sub's clothes. Styling is well done. I don't know how to explain it so I'm gonna just say it like this. They didn't make him wear like usual a rich Korean man character. He looks like he's from Italia. This style fit character so well. I appreciated the details like scarfs, rings and trouser turnups (cuffs). 5th: YOU SHOULD WATCH IT!!! Story, acting, soundtracks; everything is awesome.
