I read it in two parts. The first time I read it around chapter 80. I liked the middle two and the sand sculptures at the beginning, but the H plot became denser as it went on... I couldn't stand it anymore, so I stopped reading. I started watching it again about two months ago. I felt that everyone was very cute in the relationship scenes, and Chuuya's sexual tension was immediately heightened. However, we didn't spend a long time together, but the reason why our relationship was so deep, I can only think of the two people's personalities.
I quite like this kind of off-line charade, and I find it very enjoyable without feeling embarrassed. I even want to try it myself (I still can't do it due to physical limitations). From my personal taste, I think it's better than the previous one. I couldn't stand the last one until about 100 chapters in. Maybe it's because I was rushing to read the previous one for the second grade, but the H-stories became denser as it went on, and I almost couldn't stand the second grade.
