My god at 157 chps into the story and seto still acts like this with his way of thinking and being timid with physical stuff with her, my patience with him is gone completely, there's only so much self deprecating one can do before it gets really annoying in his case and starts to affect the overall story. Like anjou-san is your girlfriend, she's there for him mentally, shows him that by telling him that and physical intimacy as well, if they replaced his character with another ML and focused on the other couples I wouldn't mind it at all.
