Synopsis

Our protagonist, Ashitaba Kimikage, has developed such a fetish for being cuckolded that he can no longer get excited unless he is "cuckolded." No matter what woman, what romance, or what situation it is, he has a habit of thinking about his own sexual fetish, "What if I was cuckolded...?" Because of his fetish, Ashitaba has given up on romance, but deep down he still desires to "be in love"... (Source: Kurage Bunch, translated)
