Teyvat's babysitter (Male reader + little!genshin)

When you lost your brother, it'd felt like your whole world had come crumbling down. Some time has passed since then, and after realizing just how precious life is, you got your mother and your nephew, Alhaitham, to move in with you.

This fic is male reader, but to be honest I never use pronouns in my stuff that often so you can ignore it if you'd like.
