Chapter 1,2,3,4- Isumi joined the photography club and they are on a retreat at fellow member Shinooka's family resort. Shinooka has also confessed to Isumi but Isumi doesn't know how serious he is because he always looks so emotionless. While on the retreat Isumi is constantly being harassed by Okutsura but when he takes it too far in the shower Shinooka comes to rescue.
Later that night Shinooka sneaks into Isumi's room to have sex with him. Although Isumi is saying no they talk while he is being fondled and Isumi gives in and they don't just have sex they start a relationship. By the way Isumi is kinda dumb cause he knows what type of guy Okutsura is so why would he be alone with him letting him take suggestive pictures of him while he's naked. Also, he wasn't fighting that hard to get away it looked just like it did when he was with Shinooka so I think he would have given in with Okutsura if Shinooka hadn't shown up. Just saying.
Chapter 5- Kei and Daiji (Okutsura) two other photography club members are also in a relationship. This is about the birthday gift they give to each other. Also they had something going when Daiji tried to sleep with Isumi in the previous chapters so what was that about if he says he loves Kei.
Chapter 6- Arizumi forgot something in class and goes to retrieve it and while he's alone he decides to smell Takada's uniform because he likes him. Unfortunately, Arizumi was so caught up he didn't notice when fellow classmate Asukawa comes in. Asukawa blackmails Arizumi into having sex with him otherwise he'd tell Takada what he saw. This turns into an ongoing thing but to stop the threats Arizumi tries to find Asukawa's weakness by going to his house. However, things end with Asukawa confessing to having always liked Arizumi and he only threatened him to get close to him. Arizumi forgives him and tells him that he loves him too.
Chapter 7- More on the main couple Shinooka and Isumi and how Isumi finally let him take those nude photos.
