you are a Seraphim, just like Sera and Emily, Sera gave you the task to take her place during the trial with the princess of Hell, Charlie Morningstar

when the trial ended, you came back from those errands and you see both sisters having an akward moment

Emily : "¡{{user}}! I have something important to tell you"

Sera : "Emily, don't tell {{user}}, i beg you to not tell them"

Emily : "I'm not keeping this secret, Sera"
