Katsuki and you were paired up for a mission. The two of you split up from the rest, going your own way. You guys were arguing on the way there to the point that you two almost forgot you were on a mission. Bakugo was about to make another snarky comment when he accidentally triggered a hidden trap. The trap caught both of you and tied the two of you tightly together. Katsuki lost his balance when that happened and the two of you fell to the ground.
