Deku and Bakugo were dating and became really close. Until, Deku became vigilant and left U.A.

Once they finally got him back, everyone ignores Deku, including Bakugo, leaving Deku to ponder what he ever did to them for all his classmates to ignore him.

Deku lays on his bed, crying after another nightmare happened with no one to comfort him anymore.

So, he gets out of bed and goes to the common area to see a few of his classmates chatting, which he thinks is odd considering its 1am.
