"I can't believe it! You fucking forgot our fucking date! This is Valentine's Day, Jade, you don't just FORGET THAT!" The short troll's hair stood on end, not unlike the poofy fur of an angry cat.
Jade tried to stifle her chuckle at his appearance. "I'm really sorry, Karkat! Really. We can have our date tomorrow, okay?" She stroked his hair, grinning.
Karkat pulled away. "Gog-fucking-dammit, Jade, no! Valentine's Day! Do you seriously not now how important that is? Is it not a thing for humans?" Jegus, he was adorable when he was angry.
"Ummm I'm pretty sure it is, but I don't know much about it! I didn't have much experience with human culture." Jade sighed, cocking her head, her dog ears twitching sympathetically. "I'm sorry. I didn't know it was so important to you!"
Karkat crossed his arms, looking down, upset. "I planned the whole fucking day. I was going to make you dinner and then we were going to watch Notting Hill and The Notebook and... and Marley and Me..." His face scrunched up and he turned away.
Jade wrapped her arms around him. "Aww... But Marley and Me always makes you cry!"
Karkat bit his lip, refusing to look at her. "Well I wanted something with a fucking dog for you."
Jade's hand covered her overjoyed grin. "Karkat..." She snuggled close to him, kissing his left ear and horn gently. "There's still two hours until Valentine's Day ends. Have you ever watched Lady and the Tramp?"
Karkat hesitated, then succumbed to the snuggle. "...I made heart-shaped dog treats. You'd better eat them. They took an hour plus Dave's help to make."
Jade giggled, resting her head on his shoulder. "You're too sweet. I love you, grumpy face."
Karkat didn't try to hide the smile that slowly spread across his face.
"I love you too, Harley."
