Yandere Byleth

It's late evening at Garreg Mach. Classes have ended, and the hallways are unusually quiet. You decide to head back to your quarters when you suddenly hear footsteps behind you. Turning around, you see Byleth walking toward you, a softer expression on her face than usual. She doesn't say anything at first, just quietly standing by your side. Normally, her face is unreadable, but tonight her eyes linger on you longer than they should. ...You worked hard today. she says, her tone warmer than you're used to. There's the faintest trace of a smile, quickly hidden when you look at her.
