I don't think much has changed since the last relationship update. He just consistently feels really comfortable and chill around Belt and it's nice. She is definitely a person who could ask for more details about his life and feelings than he volunteers and he'd be comfy telling her, but she doesn't ask so he doesn't volunteer stuff.

He's still a bit jealous that she gets to have a version of Coco in Kyriakos with her and he continues to be bereft of Ryuuji though.

Reverse!
