Pparado Dwaeyo?

Han Seung-Ah, a vampire with a unique condition where men trigger her libido, instead of hunger. To keep herself safe, she's built a quiet life working at a company dominated by women. But her carefully constructed world is shaken when Lee Kang-Hyuk, a really handsome new male employee, arrives. While everyone else is swooning, Seung-Ah is plotting his swift departure. But her plans go awry, and she finds herself in increasingly awkward and perilous situations, battling the urge to sink her teeth into him. (Source: Lezhin, translated)
