Jump Return I tododeku

When five-year old Izuku stumbles across a strange meteor, he unknowingly travels to a world where he becomes Shouto Todoroki. Can he find his way back home, deal with feelings for Shouto Midoriya, and most importantly, save himself?

(Basically, Izuku and Todoroki swap families, but Izuku knows it. Also Izuku gains a quirk and Todoroki less OP. Also with a hint of multiple time lines, yaoi. Not beta-Ed.)
