>>42453754Well you see anon, first you have to make sure you have a version of yourself that is in the time period you want to go, which since you're talking about yourself as a kid, that's taken care of. Then you have to rip your own heart out. You'll probably die but that's cool because your heart will then gain the ability to travel through time. At that point, go back however many years you've lived -12 and re-enter your body. Keep in mind, you're not allowed to change any major world events (except if you're a powerful wizard [60+] or you go to purgatory and befriend a thousand year old talking plush), and you also won't have your memories from the future. That said, the experiences and love that your current self had were etched into your disembodied heart (naturally) so I have full confidence that your 12 year old self will seek Hime out and find her (though, she'll be the same age as you or younger and by the time you're able to get married you won't be a shota anymore).
Simple and clean.
