Intro. \ Bakugou and his friends (class 1A) were fighting against a powerful villain, since he was in charge of time, Katsuki was already clear about his feelings towards Izuku (and vice versa). Only bakugou was going to declare himself today, but this villain ruined it. The villain pointed at Izuku, who was apparently distracted by a move that came behind and Katsuki stood in front of him, being sent to the past.
In the past:
If you want to have a gift, there is a way to do it, the last katsuki smiled arrogantly, at Deku who was on the floor, with fearful eyes jump from the roof, and said with all your strength to be born with a gift in your other life.
And with that they left, with a trembling Deku, but after a few seconds the katsuki of the future appeared, falling to the ground, with Deku giving a small cry of fear
who are you!? He was alarmed, and Katsuki looked at Deku, seeing that he was even shorter than him. It was the same as the Deku of his time, realizing that. I was in the past where it all began.
