Seems to be a very shallow relationship; the guy is like, solely interested in her breasts. She's a human, not a pair of boobs. There seems to be only the minimum required story to write smut , so I wasn't invested in the story at all. The art was decent, though.
To the person who is confused of Ai's multiple boyfriends, they are different stories. I do admit that they look similar, but they are different people.
I wish there was more to this series. It was also very confusing when Ai was dating three different guys in the middle of the series. It needed more explanation. However, the pages were thrilling!!
