Kuroo takes Tsukishima's right hand in his left. Running his thumb over Tsukishima's knuckles and skin, he hums while doing so.

They are lying on their shared bed, content with the other's company. Kuroo on his side and Tsukishima on his back.

"Hey, Tsukki?"

Tsukishima clicks his tongue at the nickname but otherwise, Kuroo has the attention that he wants.

"Can I ask something from you?"

Tsukishima turns his head to look at Kuroo, "Sure." he said. Tsukishima looks at Kuroo's face, searching for the usual mischievousness but instead, he finds Kuroo's eyes are focusing on his hand. He looks… doleful. "What is it?" He knows something is up. Rarely does he have to use words such as "doleful" to describe Kuroo's facial expression and when the times ask, something is always up.

Gripping Tsukishima's hand, Kuroo finally breathes out audibly as if he has been holding his breath.

"Please don't go where I can't follow."

Tsukishima winces at the sudden force on his hand. He turns his body to face Karoo who's lying on his side. Kuroo has his eyes closed. He chews on his lips and Tsukishima knows that he won't be letting go of his hand any moment now.

"Hey, Tetsu?" Tsukishima calls. "Don't worry. I won't." Usually, it's Kuroo who reassures him when he's down so Tsukishima is not used to being the one reassuring the other (fear of messing things up still haunts him like a shadow). "I promise." I won't forgive myself if I do He wants to say more but words are lost to him. Tsukishima raises his other hand and cards it through Kuroo's hair. "I promise." He coos and squeezes Kuroo's hand back.

Likewise, Kuroo does the same.
