The first one is the theme song for the love between Lee Min Ho and Park Shin Hye's characters called "Moment". It's by none other than 2AM's Changmin, who incorporated his vocals to deliver the message of the blossoming love between the two characters.

The second song is by VIXX's Ken, who lent his powerful vocals for the track titled "In the Name of Love". You might have heard this during the episode that aired on the 17th.

Finally, last but not least is "Two People", which is by Park Jang Hyun and is actually a remake of Sung Si Kyung's song released back in 2005.

Without further ado, check out the three tracks below to decide which one you like the best!
