I must say the concept of this drama is pretty good but was it well executed ? NOPE
A slight disappointment because it started as suspenseful, but kinda just faded out to where it didnt really make much sense..

The female lead is an actress. She is in her 30s and is about to get replaced by another actress who is younger than her. She decides to share some gossip of that younger actress , which results in the younger actress attempted suicide. Female lead attends a high school gathering and is sent a video/ recording of what she did. She finds her old mp3 and finds out that it can connect her old high school self. She starts to suspect all of her high school friends.

She has two best friend and two guy friends ( who both like her) . One is always bickering with her Yu Ming. The other use to be a chubby kid, but now is tall and handsome.

the story focuses of her high school trying to fix up the relationships and the things in order for her future self to figure out who is blackmailing her. it flashes between her high school times and current actress time.

Too much, back and forth without much progression made it a little dull. Like there was nothing really revealing who it actually was. She just literally went down the list. I was just as confused....

There is hardly any romance up until the very end... so wouldnt reccommend for romance.. It had potential like but eventually all the excitement/suspense fizzled out...
