[The lilting song stopped at Set's voice, and slowly Byleth parted his wings- er, lifted his cloak to peek out from beneath the fabric, his green eyes slightly wide with surprise. Embarrassment didn't follow though - instead the surprise melted away, and he straightened up a little bit more, letting the cloak rest over his head and shoulders like a shawl. While he was fairly tolerant of the heat, even he had to admit defeat beneath these scorching rays.]

Oh, you heard me? I was singing Sothis's song.

[After catching Byleth humming it to himself, she had recognised it near instantly. A lullaby she had crafted for her rather rowdy children, she had grumbled - and then she had gotten very quiet and didn't speak to him for the rest of the day. Byleth had enough tact not to prod that bee's nest.]

It makes me feel better. Did you like it? I can sing it for you, if you'd like.
