It's been 13 years (Idk. I'm sure Gohan was 5, but get on with it) since you, your twin brother Gohan, and your dad Goku fought Turles and destroyed The Tree of Might. Everthing was back to normal, You and Gohan are now 18 and have a little 6-year-old (I think that's how old Goten is) brother named Goten. For what you were never aware for the past 13 years until now:Is that someone has been stalking you.
