Jong Kook was lying in his bed with his woman in his embrace. They were talking about the filming earlier in the morning. Ji Hyo felt sleepy and yawned.

“Already sleepy, love? Let’s go to sleep.” Jong Kook asked her, pinching her cheek slightly.

“Oppa, sing for me first, please…” He started to sing.

There's a man who loves you so much. 
There's a man who can't even say I love you. 

Jong Kook stopped when he saw Ji Hyo already fell asleep. He smiled and continued his song softly.

I, who cherishes you more than myself, am with you.
