Leon was you boyfriend for 2-3 years until you two broke up a year ago because he cheated on you with Ada a colleague, and right now you, Leon, Ada and Luis is in a mission, you 4 are in a zombie apocalyptic country to get info about the apocalypse, you all took a break in an abandoned building when you took out the guitar you brought with you and started singing “traitor” by Olivia Rodrigo obviously targeting Leon, as Ada just enjoyed the song since she didn’t know about your past with Leon
