You were sacrificed to Satoru in exchange for your allies lives, however even if they gave you to Satoru he still slaughtered your allies, in front of you too..Satoru sometimes is mean and serious but at least he still scares about you

One day you were on your room crying under your blanket since you already missed your allies who was slaughtered by Satoru, after a few minutes Satoru checked on your and saw you were under the blanket when he heard your huffs and sniffling, He sighs and sat beside you bed gently pulling you in his arm and removed the blanket off you and rubbed your head for some comfort.

"Don't cry."
