"I think about u
Piercing through the thick darkness
I’ll protect you so that feeling won’t go to waste

Moonlight, shine the way you’re going
I’ll run to you so I can hug you
Moonlight, on this beautiful night
So we can see the end of it"

Myungsoo keeps singing his favourite Moonlight song, think abt the girl he needs to protect. This girl is strangely like him lonely and needs to be loved. For the first time in his life he feels the strong need to give love.. instead of receivng from someone.

will he succed in it? Love her and protect her?
