I am across this movie by chance when I was surfing YT for a new drama to watch. What made me click it was Dennis Oh. That man is dreamy! * swoon*.
Lets see the premise of this story was cute. Two insomniacs fall in love gradually. It was a nice change of pace from the normal dramas I watch.

ML was a rich, somewhat self centered hotelier vying against his younger brother for ownership of their father's hotel.
The FL was a ordinary girl that never sleeps finding the perfect job of a hotel tester.

I like that there really wasn't any second lead syndrome at all. It wasn't just a wham bam we are in love instantly type of drama. Even though I would consider this a romance movie, I definitely would not say the romance was really prominent.

These two leads worked well together and you could see the chemistry. I must admit I really found the younger brother very very annoying. I kind of wish he wasn't in this drama. * kicking him to the curb*

Music. eh it was mediocre at best. I didn't really pay attention to it.

Re-watch value, eh I would re-watch it for Dennis Oh spectating only.
