Korean Drama - When Its At Night MVs from Youtube

I have been following this drama which is showing on Starhub Cable TV channel 55 every Sunday, 10.30pm and the show has been getting more and more interesting. The 2 main leads show great chemistry together and it was also quite comical seeing them bickering constantly. Lee Dong Gun was real cute and charming as Kim Beom Sang in the scene where he tried to kiss Kim Sun Ah's character Heo Cho Hee in episode 6.

Lee Joo Hyun also looks cute in the drama acting as captain Kang Shi Wan, a widower with a child who works with Cho Hee to recover lost national treasures. Cho Hee had a crush on him initially but he was not ready for a new relationship after the death of his wife and Cho Hee finds herself developing feelings for Beom Sang instead. I have been listening to the drama's soundtrack and love one of the song which was constantly played in the drama but do not know the name and have been unable to find it in Youtube to share with everyone. However i have found some nice MVs from youtube to share with fans of the drama:
