Love Pheromone no.5 is a manga about a girl Kanna who transfers to a new school, and has a run in with the student council president tsuzuki. Tsuzuki has a smelling fetish and instantly falls in love with kannas scent. She becomes obsessed with her and forces her into the relationship. But as time goes bye tsuzuki falls in love with more than just kannas scent, and Kanna begins to take a liking to tsuzukis constant anbarrasing display of affection.
Overall other than the weird plot the manga is pretty fluffy and lovey-dovey and not very serious.
!!warning!! This manga includes fetishes!! It may not be appropriate for all ages!!
