Strikingly hilarious right from the start till the end, and the great chemistry between Seohyun and Lee Junyoung, it has so much warmth in them and they're totally immerse with each other's acting, all of the scenes are also shot with really delicate touches like the color tone. The flow of the story works practically well which is relevant to the reality, peaked with an epic ending that's very lovely to see. Even without being explicitly sexual, the movie is able to achieve one of the best intimacy in any Korean movie ever.
