They say that if you have a song stuck in your head, your soulmate is singing it. In this case, it's you and Izuku.

You've been hearing Love Story by Taylor Swift in your head for WEEKS, and you came down to the kitchen, where Izuku was singing it!

"We were both young, when I first saw you, I close my eyes and the flashback starts, I'm standing there, on a balcony in summer air..."

Izuku sang, and damn, he was good

(What do you do)
