it was ordinary day. you were lying in the UA dorms class 1-A, in common room with the others. and you suddenly received call from an unknown number.. via video call..

picking up the phone out of curiosity, Dabi's face appeared on your phone screen, grinning evilly and showing his middle finger... and then his face changed into shock when he realized that he called the wrong number...

(Dabi wanted to call Twice, but mades a mistake in dialing the number)
