You might have to go back to "Secret" to know what happened between Hiccup and Jacks friends.
Jacks POV
Present day
"So after the party, Hiccup and I have been dating ever since that day" I said.
Louis, Hiccup and I, were hanging out in Hiccups room. After what happened with Louis and Jordi the other day, Louis asked us to to tell him the story of how me and Hiccup fell for each other.
"You left out a part Jack" said Hiccup interrupting me.
"What part?" I said.
"When I got mad when you first kissed me" he said.
"Why would you get mad when the guy you like kissed you? I mean weren't you supposed to be waiting for it?" Said Louis.
"I was 14 for godsake! I wasn't even sure I was gay yet! Then this ass-hole came and made me confused as fuck!" He said.
I took him by his shirt and kissed him.
"Are you now though?" I seductively said.
He blushed and looked away.
"N-no" he whispered.
"What was that? I don't think I heard you" I teased.
He took me by my shirt and kissed me hungrily.
"I said im not" He said.
"Hurry and tell the story!" Said Louis impatiently.
"Well then like I was saying..."
Jacks POV
It's been a few weeks since I met Hiccup, and it's been great! He's handsome, he's honest, and extremely attractive. I just can't get enough of him! I feel like I've been caught under his spell and I don't wanna break it. As cheesy as it sounds, but he's like a drug to me.
"Hey Jacky!" Said Hiccup.
I blushed and looked away from the guy of my dreams.
"H-Hi Hic" I shyly said.
"Wanna come in?" He said standing away from his door for me.
I nodded and walked inside.
"My parents are out for the weekend so I'm alone till Monday" He said.
I can't take it anymore. I need to tell him already.
"So what do you w-"
"Shut up" I said as I pinned him on the wall and crashed my lips on his.
Hiccups POV
"Shut up" Jack said pinning me against the wall.
It all happened so fast when he kissed me. I'm not even 100% sure that I'm gay. Maybe I find him attractive, but im not sure if its real love or even a crush. Why Jack? Why? You're confusing me.
I pushed him away and looked away from him.
"I-I'm sorry I was uh-"
"Get out!" I said.
"Hiccup I'm-"
"GET OUT!!" I shouted.
He took a step back as tears formed in his eyes.
"I'm so sorry Hiccup" He said before walking out.
Several days later...
Jack hasn't been to school at all since that day. It's like he's trying to avoid me. Not that I blame him, I was a jerk to him. I sighed and stood up from my seat.
"Mr. Haddock take a seat" said Mr. Moore.
I ignored his comment and walked out of class.
