In my dreams

Izuku is a prime omega who dreams of being a doctor for pro-heroes one day but being a prime omega is hard because there are hardly any jobs for omegas much less prime ones and if there was a job for them.... they'd be on their feet all the damn time. After a day out in town with his friends he gets teleported to a different world, a world much different than his. he gets used to their way of living, their rules, their tradition. everything is going perfectly fine except for when he goes back to his world. he now has to find a perfectly good excuse to tell his friends about his absence, he has to find a way to keep the secret to himself.
