Based on a prompt from the Monster Girl/Boy generator: "Bad siren boy who wears thigh-high socks and loves Accountant."

I went with the more birdlike interpretation of the siren, rather than the aquatic, mermish sort, since that's both, I believe, more accurate to the older stories and a lot more fun, because, i mean, wings!!

Also though I drew this forever ago, I still kind of think these two are a really cute couple, haha ^^ <3
