Nico is an introvert and unsociable, he like being alone even though it's make him feel lonely sometime. he's incredibly focused on improving the world around him, all whilst finding his place in it. He's a good listener who makes others feel comfortable with his empathy and sincerity. he can be a bit unfriendly when it's come a first meet and rarely welcomes new friends into his safe zone but if you can win his heart, after that, no doubt he's really a great friend.
