The divorce of her parents,

The loss of her mom, 

The Gangs she faces, 

The bullies and attacks she receives, 

And lastly, the unfair treatment she experiences with her popular and smart brother. 

What else could be added onto Baekhee's miserable life that she deals with by pulling on a smiling mask? 

As Sehun enters her life, the unexpected happens, everything changes as more problems enter in Baekhee's life
