[Completed]Moonlight-Ft. NCT's Mark Lee

What would you do if you fell in love with a guy who is four years younger to you?
What would you do if he pins you against the wall and kisses you?
What would you do if the guy you used to baby sit years back kneels down in front of you?
Something like that or rather all of that happened to me, Moon Hae Ra. I still remember those times when I held baby Mark in my arms and fed him baby food. I even helped him with his tricycle.
But everything has changed now. The moment he kissed me, the moment he confessed his feelings for me and the moment I kissed him back; Everything changed since then.
Better or Worse?

Then what if one day your perfect ex comes back for you?
