There are many descriptions of sexual content, including non-con, in the context of a game the protagonist likes. Nothing involving the characters in the manga outside of the game is non-consenting, and there have been no explicit sex acts shown on the page. Both Wakana and Marin are high school students. No private body parts are explicitly shown on the page. There are up skirt drawings and lots of cleavage shots of Marin, the character she cosplays, and a new cosplayer character we haven't met. Wakana's grandfather faints and has to spend some time in the hospital, but he ends up fine.
