You'd mentioned it a few times, the foreign concept for Todoroki, having love for your father, Todoroki's always preferred his mother through and through, rightfully so- so it did shock him a little to hear someone who prefers theirs, when he hates his with a burning passion and does most things he does to spite Endeavour- so to hear about this from you in passing made him curious, so when he next saw you in the common room on the couch, he silently walked over and sat beside you somehow he always has perfect posture- after a minute of plain staring at you, you hear his deep voice speak up

"Why do you like your father?" Now for you this is out of nowhere, but hey, Todoroki asks strange things all the time
