Jack's POV
Rapunzel was checking her mail when...
"Guys!", she yelled.
"What is it?",I asked.
"Look!", she showed us an invitation.
"Who sent it?". Merida asked.
"Elsa did."
"For what?" , Hiccup asked, " Elsa almost never sends letters or invitations."
"Hmmm...It's for Anna's birthday! It says it's on Sunday."
"I can't come! I have archery training.", Merida was very sad.
I agreed to go and I was the only one who could go. Rapunzel was sad 'cause the others couldn't come.
Elsa's POV
"Elsa!", I heard Anna yelling , "Did you sent the invitation to Rapunzel?"
"Yes. Please just don't yell!", I told her.
"I can't wait until Sunday!"
"Well I can!"
Days passed quickly. The day of the party came. I saw Jack and Rapunzel searching for me and Anna. When they saw me , Jack waved softly and Rapunzel ran over to us.
"Hi! Happy birthday , Anna!", Rapunzel said.
"Thanks!"
"Hi girls!", Jack said.
I was pleased to see him. He pulled me away from the others. He asked me to be his girlfriend and I agreed with my whole heart. When we went back we told the girls about us and they both gasped when they heard it. I just couldn't understand why.
