Ryuutaro shrugged almost unnoticably as he gracefully stepped over to them. He wasn't shy after all and he had to make very sure it would not be mistaken for it.
When he reached the group, he leaned against a wall, fan half-opened in his hand. While he didn't use the item a lot around Hayato anymore (it was just so impractical, he needed his hands then... walking around holding hands and needing another to open doors or carry something that already made for difficulties after all), he would always make sure to use it a lot when around others as well. It was a part of him, a part of his personality that he needed to make sure to come accross just right.
Hayato knew him anyway and beyond the boundaries of what he'd usually let people see, so with him... he could put the fan aside and only use it when it came natural and he felt like it. ... fanshushes tended to be needed one time or another after all

Ryuutaro still did not take part in the conversation though, not because he would be too awkward doing so, but because what he wanted was listening. Listening and looking pretty seemed like the perfect strategy right now. ... admittedly he tended to be better at the later and problematic with the first.
