OK, so I really put off watching this drama based on the hot & cold reviews here and I am glad I did watch it.
I don't get the hate towards this Drama, especially those saying some episodes are worthless (especially 14, 15 and 16).
Anyone who has watched more than 5 dramas could tell what they were doing and where this was going to go... They need to create drama, they need some redeeming arcs, they need some noble idiocy (I abhor it, but it's fairly common in dramaland).

I loved the chemistry between the leads and the cleaning team, they all worked well together. Made me laugh, cringe and even brought me to the verge of tears. Some moments I will rewatch as they cracked me up.
