Jackson was usually a very jealous type, especially when it came to Mark. But nonetheless, he fought himself through his jealousy and let Mark breathe even when other people were performing some obvious flirting with the flying member of GOT7. 
One time he actually did lose his cool. JYP had a gathering for all artists and actors and Mark had been talking to Nichkhun for a while and Jackson didn't like the way Mark was smiling at Nichkhun. Jackson hated how he felt. He didn't want to be jealous of Nichkhun because he knew Nuchkhun wasn't a threat in any possible way. All JYP Nation knew of the Markson couple and no one would dream of separating them.
"I'll be leaving.", Jackson mumbled to Jaebum and headed for the dorm to go back to the dorm.

Jaebum could tell what Jackson's problem was when he noticed Jackson glaring at Mark and Nichkhun and went to get Mark.
"Your loverboy is quite concerned."
"What?", Mark asked but knew what he meant. He sighed. "Thanks Jae, I'll go check on him. Nichkhun-hyung, it was nice to talk to you, but I gotta go."
Nichkhun laughed. "We can talk more another day. Go get him."
Mark bid goodbye to everyone and headed for the same place as Jackson did not too long earlier.

"Jacks?"
When no one replied, he went to the kitchen and found the person he was looking for, with phone in his hands, pretending not to notice Mark.
"What's wrong?"
Jackson didn't reply. Mark sat down next to him and grabbed his phone to put in his pocket.
"Please?"
"It's stupid."
Mark hugged Jackson.
"You don't have to be so insecure. If anything I should be."
"No-"
Mark interrupted Jackson by placing his lips on the younger's.
"Not a word. I won't ever cheat on you, Jacks. I'm only in love with you and no one else. You've put a lock on my heart, and you own the key."
"Yah, don't be so cheesy!"
Mark laughed. Jackson grabbed his hand and hugged him back with his free arm.
"I love you."
"I love you too."
They sealed their words with another kiss.
