Leia was raised by Vader, and they both know her brother is out there somewhere. Obi-Wan senses their arrival on Tatooine and he and Luke get a fairly good head's start.
Han is assigned by Vader to intercept Luke and Obi-Wan and convince Luke to come with him and return him to his family.
Han finds them, not knowing the full details, and when he finds Luke, decides to seduce him.
Vader is furious when he finds out, but Leia sees how they can use this to their advantage. Luke is so naive and has fallen utterly for Han, and Han is starting to for him (and feeling very guilty now he knows the kid is actually innocent and unprepared for whatever the Empire has in store for him).
Leia insists they can manipulate Luke and Han into turning to the dark side, since Luke is struggling dealing with any affection from Leia and Vader and has latched onto Han instead.
