Especially For Us (discontinued)

Park Jiwon (Eu) has gone through a terrible incident that didn't have to do with her at all but she did anyways and someone saved her. That someone goes by the name of Mia (Han Eunji) but sadly Jiwon couldn't remember who saved her as her memories are blurry. Mia on the other hand has made a promise to herself that she will do anything to save Jiwon even if she doesn't know her that at all.
