OH MY GOD! Such an amazing kdrama! I wasn't about that should i watch it or nah. But i watched it and it worth! Amazing cast, ost, story. Sooyoung and Jang Hyuk became one of my favourite actors, amazing acting, Jang Hyuk's character has some good fighting skills. Idk which episode's ending was that but that ost was really good! I would love to see Sooyoung in more thriller dramas. If you are tired of romcoms i definitely recommend it! It has a really dark vibe that i really liked. Some points really surprised me tho, especially when Sooyoung saw those corpses
