Bakugo and Izuku had crushes on eachother, but they were too scared to say anything.

One days, Bakugo had stumbled into Hatsume’s lab and saw some water. He had just come back from training, so he drank it.

Izuku followed inside. “Kacchan, wait up!” He called out with a grin, then saw Bakugo drinking the water. “Kacchan, what is that??” He asked.
