I'll Let You In (Just Don't Freak Out)

It was a moment of weakness. It had to be. Otherwise, why would Atsumu ask that?

-

"Want to meet my grannie?" Atsumu blurted out, overcome with liquid courage and adoration for his Kiyoomi.

He almost didn't realize that he said it until Kiyoomi pulled away from him and sat up, placing his hands on Atsumu's shoulder. Atsumu whined at the loss of warmth before noticing the shock on Kiyoomi's face. He sat up as well.

"Love, what's wrong?" he asked as he reached up to caress Kiyoomi's cheek.

"We can go meet your grandma?" Kiyoomi whispered.

"I already met your parents. It's about time you met my gran," Atsumu teased. "She'd love you anyway - I just know it."

Kiyoomi took in a breath before suddenly hugging Atsumu tight to his chest.

"Omi...?"

"I love you, Atsu," Kiyoomi said, muffled by the way his head was nestled on Atsumu's shoulder.

Atsumu grinned as he gently pulled them back down to the comfort of the bed. "I love you too, Omi."

-

Past Atsumu, he decided, was an asshole for doing this and making Future Atsumu deal with it.

AKA Atsumu has to figure out how to hide the yokai in his house from Kiyoomi.

Just great.
