I'm An XL. Could You Find Me A Spouse?

Minato works as a counselor for a matchmaking company. For some reason, he often gets stalked by his female clients. He switches to taking on male clients, believing he is making a fresh start, but his relief is short-lived... His first client, Akihi, is a handsome and high-profile man who unfortunately suffers from sweaty hands, which has given him an inferiority complex and made him into a closet pervert. When Minato shows Akihi some kindness, Akihi falls in love with him!! He begins to pursue Minato, regardless of their genders. Right in the middle of the consultation, he pushes Minato down, drops his pants, and declares, "I want to lose my virginity to you!"
