Have not watched the latest episode but the lyrics for the song is so beautiful and apt.
Kim Dong Ryul – Like A Child
When you tell me that you love me and accept me
I say to myself confidently that I have nothing else that I need
Although I feel ashamed with my growing greed,
I think about you all day again
and I feel fidgety.
I have a lot of envy (like a child)
I have a lot of fears (like a fool)
I can’t believe that right now you are near me smiling
I’m so happy that it’s so unbearable to me
I fear that when I open my eyes, every thing will disappear
So I can’t fall asleep.

I want to give to you (my every thing)
I want to receive from you (your heart)
Everything that everyone else does, I want to share with you
But because my heart is too hasty and too narrow-minded,
I fear that I might ruin everything
So I grow uneasy.

For making me smile (like a child)
For making me cry (like a fool)
For allowing me to feel this flutter in my heart one more time
For letting me trust you, for being a strength to me
So the first thing I’ll say when I open my eyes
Thanks so much.
For coming to me
For letting me dream
For giving me the present “Us”
I love you
