Help me find this drama?

A couple of years ago on Netflix, I started a drama. I cannot for the life of me remember the name or any of the actor’s names. All I remember is that it involved a girl, I think school age, having these little dolls that turned into idols I believe. I’m sorry I don’t remember more.

Is it " Border Town"? or Backstreet Girls? not sure this are what google are recommending to me based on the information you provided.

Do you remember which theme it was? Thriller, romance...?

I’m pretty sure it was romance! I’m sorry I can’t seem to remember a lot about it!

I'm pretty sure the drama you are looking for is Dream Knight. It was on Netflix back in 2016. I've watched it and everything you mentioned was in the drama. 

Hm,  okay! I’ll definitely check this out. Thank you for your help!
