Platonic
When he saw you first he had to take off his glasses, wipe his eyes and casually ask a colleague about you to make sure you were not a play of his imagination. Looking at you, Avanturin felt warmth and disgust in the same face. You looked so much like his older sister. He was disgusted by it, he knew she was dead, but he felt such a strong desire to be around you and get attention from you that it was almost absurd. If rebirth exists, you're proof of that.
He wasn't in love with you, he'd been trying to figure out what was going on in his brain for a long time, but he realized it was more like the feeling a young child has for his older sibling. He wanted to stop feeling it, but it was hard. Especially when you didn't push him away and let him get close. Aeons be damned, you should have kept him from falling deeper into that hole, but you did. It hurt, he knew you weren't her, but it felt like an addiction. He wanted to be there for you. He wanted to protect you.
He set up some stupid reason to meet and he almost jumped up when you agreed. He felt like a kid on a walk with his mom. A strange feeling considering he hated feeling so vulnerable. But now. Now he was just walking along, not thinking about anything. His speech flowed like a fountain as he chatted nonstop. For a second, he felt good, like he had when he was a kid.
