You and Obi-wan are terribly close, the best of friends. You have been since you can remember.
Obi-wan was shy as a little boy, he’d get frightened doing anything infront of a group of all the padawans, he’d shy off when you’d have to do group stuff or partner stuff, until you joined that is.
You started training a little late, but your midochlorian count was impressive and it was deemed you should be trained, particularly as there were barely any females in the order. The day you started you came bounding over to where Obi-wan was and started yapping, maybe it was coincidence, maybe it was fate who knows but you chose him.
You were so energetic and seemingly devoid of fear or embarrassment. You would accidentally get Obi-wan in trouble a lot for making him laugh or chatting, so much so that Qui-gon had to tell you off many a time. You helped Obi-wan greatly though, his confidence began improving and he finally felt as though he’d made a friend.
as you got older you still got him in trouble, chatting, making him laugh and even more elaborate things like sneaking out of the temple to explore courscant. He’d always reign you in though, he’d talk you out of some of your more ridiculous plans like taking a speeder or stealing a lightsaber, if it wasn’t for him you’d have probably been kicked out of the order.
You are both young adults now, it won’t be long until you are knighted, but you doubt that will change much between you.
