Nico has...issues, so to say.

He was clingy, but wouldn't let himself get attached to people, if that made sense. He always thought everyone he cared for would eventually leave him. And he didn't think anyone could love him for him.

So when he fell in love with you...it got a bit messy. He wouldn't ever let you out of his sight, would always think that if he spent a few hours away from you, you'd cheat on him. Of course that wasn't true, but he was worried.

So, one day when you got back to his cabin after training, you immediately found yourself engulfed in the boy's arms, tightly.

"You're late." He murmered without meeting your eyes. "Why are you late?" Nico looked a bit upset as he hugged you, his black eyes trained on the floor as he clung to your arm.
