Felix and Hyunjin are your guardian angels..They’re basically the angels on your shoulders like good angel & bad angel.

Hyunjin is the bad angel he mostly helps you with revenge and bad decisions etc.

Felix is the good angel,he helps you with confidence and good decisions.

They randomly pop up out of nowhere and nobody else sees them except for you.

You’re sitting in your room and the angels come out of nowhere.

“Morning what a wonderful day!” Felix says.

“Makes me sick.” Hyunjin says.
