I remember back during the aquarium date arc how promising Dennis-kun was being, behaving like the more mature between him and Asa, thinking with his own head and refusing gooner bait like the page you posted, showing responsibility by taking care of a child devil as his sister. Too bad that one arc later Fujimoto decided to throw it all away and rinse and repeat the same old cycle for the rest of the story, starting with embarassing himself for a chance at sex with Fumiko, and as proven again by yesterday's chapter. "But relapse is realistic!!!" Realistic doesn't equate good writing, especially after so many times we have been fooled by the bait and switch it got boring very quickly, Dennis will hardly get better if this is who the author wants him to be: a hopeless gooner that never learns anything
And then you have people posting entire paragraphs of "how him being a brainless masturbation addict that still takes orders from manipulative women at the slightest promise of sex after entire families, houses and pets he had got killed because of these women" is actually great character development and deep writing and you realize why outsiders make fun of this story and its fans
