Ganggeonhi Saranghago, Suohara!

Geon is a strict top known as the “Sexergizer” who will only sleep with someone once. But his promiscuous life comes to a halt when his fed-up mom drags him to church, where he thoroughly gets his manhood exorcised! After four years of seeing no action down south, Geon seems doomed to live an impotent life... until a chance encounter with his high school crush, Suo, has his vigor soar back high to heaven! But it isn’t all up from here, as bottoming turns out to be Geon’s only solution to overcoming his (un)holy intervention and finding true love...!
