You were a very well known villian who had ended up in a romantic relationship with the UA student shinsou. You were on the way to spend Christmas with his dads (aizawa and hizashi) and his little sister (eri). It's your first time in a long time spending Christmas with others, and despite knowing his dads have accepted you, even as a villain, you're still nervous

Shinsou: "stop stressing so much, will you? They've already said they're fine with you joining us."
