I'm in love with HIM??!?!?!? (Billdip)

Going back to gravityfalls?!???

(Dipper and Mable are 18 in this and I might not be able to post all of the time because of school I hope you guys understand 😁)

Dippers POV:

me and Mable where on our way back to gravity falls to live with the Grunckels, we haven't seen them since we where 12. I am really exited to see every one again. "DIPDOP WE ARE HERE!!!" She says while shaking me as we passed the gravity falls sign. I felt sick, what didn't help was that the bus was going up and down on the road because of the bumps. "M-Mable stop I think I'm gonna be sick" I said as I put my hand over my mouth Trying not to through up. "SORRY DIPPER!!" She said then stoped shaking me. The bus stop I realised that we are at the bus stop as me and Mable got off the bus we saw two old wrinkly men. It was Grunckel Stan and grunckel Ford. Mabel runs and hugs them."GRUNCKEL STAN GRUNCKEL FORD I MISSED YOU GUYS!!" She shouted. I went to hug them, they hugged back. "Welcome back kids" Stan said. We started to walk to the mystery shack. Mable being Mable was blabbing off to the Grunckels about back home and about how she realised she was a lesbian and the Grunckels were shocked at first but obviously accepted her.

At the shack

Me and Mable put our stuff up in our room and went down stairs I see Mables friends, Wendy, soos, Grunckels, and pacifica. I walk down the stairs and say "hey guys" "hey dipper it's been a long time" Wendy says then pulls me in for a hug and laughs.
I let go of the hug and say my hellos and give my hugs to everyone ( except the Grunckels bc he already did at the bus stop). They hang out for a while until it was time for bed they all went to sleep.
At 3:00 am dipper wakes up to get a drink and goes up to the roof for a bit to relax when out of nowhere ????? Pops out of nowhere. " ????HOW-WHY ARE YOU HERE?!?!?" Dipper asked scared and angry at the same time.

I know it's short it's just I don't know what to do also could you guys give me ideas? That will help me out so much.
