who don't drink blood but lick main male character sweat as source of energy

lol.. licking sweat.. from which manga u got that idea tho?

At first, I thought it was Rosario to Vampire, but when I heard licking sweat, I knew something was wrong...

I honestly don't remember since it's been quite a while since I read it, but you could take a look at Inbura! - Bishoujo Kyuuketsuki no Hazukashii Himitsu ..........yeah, don't remember, but it was vampire babes and ecchi / borderline content, so maybe 😀

Good luck finding it 🙂
