You're in the UA gym, training, listening to your favorite song through your headphones. Your best friend Bakugo walks in the gym to train as well, when he sees you, as you quietly sing along to your music. He walks around you, not interrupting. You continue training, not noticing Bakugo

You continue training, and after a while, you notice Bakugo training near you as well. Bakugo treats you like his sibling, and gave you the nickname "Sunshine".. though he won't say why...
