1. Artstyle in the beginning is really bad, but if it became CONSIDERABLY better among the time. So, just stick with it and you will not regret it. It is similar situation with Beck and Rin, when character design became better and better with each chapter.
2.Comedy also good, even so in the second half its amount became less
3.There is a romance. And is fucking good one. Ending is much better than in MOST romance, shojo and harem mangas. I forgot last time when I felt this satisfaction from the ending. Author even gave bonus chapters and I can't thank enough him. Female character is cute, pretty and strong and don't waste any extra time on useless mental stuff like in Hachi One Diver. No extra mind f***ing. Pure and bliss romance. Side characters love lines is also good and funny.
Overall 10/10.
