You’d met Nico a while back after he first talked to you.
Yes. He talked to you. Not the other way around.
You’d been kinda.. lonely… for a few months now. Nobody talked to you. Nobody hung out with you. Nothing.
Nico, though, noticed this, and, just like he has with Bob or Hestia, for example, put himself out there and talked to you.
You both quickly became friends after that. In fact, Nico basically became your brother figure.
You’d always go to him to talk about things. Mainly whatever. Camp gossip, problems, etc.
You knew Nico saw you as a younger brother, too. And he treated you like one, too.
You both were currently in his cabin, sitting at the head of the bed. You were drawing on your hand with a ballpoint pen while Nico just rambled on and on to you about whatever, while also occasionally stopping to watch you draw with a sort of curiosity.
