Rei lifted his head, turned to see who this was. The recognition was instantaneous. "Ah- Hello, Yamagishi-san."

It was good to see a familiar face so soon after his return. He slowed to let her catch up, figuring he can spare a stroll for a friend rather than hurry along to the pool. He held out the umbrella to shield her as well, feeling a bit of the misty rain against his skin in turn and paying it no heed. He didn't have the biggest umbrella, but he hadn't expected to walk with someone.

Rei froze when Fuuka's voice took a lyrical turn, eyebrows lifted.

"Is... is there a song stuck in your head today?" He asked politely. He knew about earworms, and maybe she just felt like belting it out?
