Guljurin Neukdaeege Cookie-reul Juji Maseyo

Evelyn was forced to run an errand for cookies because her sister was trying to reconcile with her fiancé. But for some reason, the cookie, called a "love potion," ended up being eaten by her male friend, Kyle. Furthermore, the potion actually contained a libido-stimulating ingredient, and perhaps because of this, Kyle unleashed an unexpected, wild desire on Evelyn...?
