You and katsuki was walking together, when a white cat with pretty eyes caught your attention. For some reason, you follow it. You follow the cat into a dark alley, you was about to pet it until it meowed and a portal appear underneath you. You fell and everything went black

Once you open your eyes, everything looks the same. You try to find Katsuki but accidentally bump into someone

“Watch where you’re going!” He said and when you saw his face, it was katsuki…. BUT OLDER!
