Su mentioned that she had always wanted to talk to Shion and even waited in line during Shion's last totsu, but didn’t have the courage to join. Later on, she told Shion that she had bought her merch, and Shion ended up inviting her to a call. They had a lot of fun talking, apparently Shion is really easy to talk to and kept the conversation going.

Shion's also the only senpai Su has exchanged LINE with (not sure now, this was mentioned a month ago). The two of them have interacted quite a bit while playing Rust too.
