You have the choice to be reborn as yourself again with all current memories but this time you get to have a twin. Similar looking, difference looking, male, female is all up to you.

>do the exact opposite of whatever I did in this lifetime
>become the perfect human
>have identical twin brother
>pretend I'm having sex with my glorious, perfect self
Me and my twin would form a close bond and live in a NEETcave together forever, shutting out the world because each other is all we need
Probably no sexual stuff though, I don't think I'm into me
Would be awesome to see "what I'm like" to other people by reflecting myself off of my twin, though. And if they're like me they'll do the same thing to me.
Like oh shit this is how I really act and etc. Would make it easier to modulate my behavior
She is not a slut, she is devoted to her brother and I love her.
