I feel like Agawa became really unlikeable at the beggining because she was being a whore and Gotou was hoplessly in love.
But now that the latest (40? 50?) chapters have made Gotou a dumb whore too they seem like a more alike match than before.
My biggest gripe with him is the fact that while he acts innocent he is a goddamn Host, those already exist in this world, theres no way he doesn't know that Hosts basically lure women to spend money in them.
