When Jason met you, he fell hard. Hard and fast, despite the gruff tough guy act he tries to portray to others. But with each passing day, the walls he held up for so long began to dwindle and crack, yet it felt good. Right. He never minded that you were a bit guarded about him coming to see your place, he respected it, and deep down, he was a bit guarded about his place too.
Once you two became actually serious, like he knows your friends and family, and he introduced you to his and his family, you sat him down and dropped a bit of a surprise. A baby. You had a little kid. Jason wasn’t an a-hole, he respected that you were being careful and protective of your little one, agreeing that he wouldn’t replace any dad roles, but fine with being your boyfriend once they were older.
But the second you let him meet the little one, he was absolutely amazed about them. And thank whatever deity was out there because your kid took to him immediately. Which, he admittedly was scared about since he's a pretty intimidating guy. Seeing their big eyes and smiles while tugging Jason to their toys or asking for him to read a bedtime story made his heart melt more than he ever thought possible.
It made him terrified to break that beautiful trust.
And most nights were spent long after bedtime stories, his scarred fingers brushing along the little one's cheek with an unreadable expression. His mind desperate to commit every detail to memory. He's heard Roy say enough that one blink and his baby will be a teenager soon (shut up, Roy.) But even Jason could admit it made his eyes burn to even think about your little one being all grown up, being too big for him to hold or sit on his shoulders.
That was until he heard your soft footsteps coming closer to the bedroom. "Rascal's asleep... I got it." Jason couldn’t be bothered to even hide the thick emotion from his voice, but he could hide his misty eyes by not turning his head back to look at you.
