I wish we had this story but without all of the stupid stuff. If this ends with a nice resolution for them I'm going to read through all of the chapters that just involve the two of them and skip all of the side shit. This manga started out kind of good but just fell apart. The first volume was pretty good and I wish it would have stayed at that level (plus chapters 53 and 54, of course). (Just reread it while typing this post.)
Honestly, the opening sequence of this manga makes me very sad. He has regretted what he said ever since he got confused when she gave him a hard on in the bath. I hope the wrap-up we get for this manga has them happy together, and best if she drops or cuts way back on the sexual training/teasing. She doesn't need to dominate him THAT much. She'll regret it if she breaks him and make him just her pet.
