Manga Diary of a Male Porn Star manga volume 4 features story and art by Kaeruno Erefante.

Though he’s been in the industry for over a year, Kaeruno still feels like an amateur porn star. He’s still learning all the ins and outs and encountering new kinks and subgenres like watersports, lawful lolicon, and squirting. On top of that, he starts to get curious about what happens behind the camera. All the while, he’s still seeing his beautiful sometimes-costar Yuri-san on his days off, and his feelings for her are growing stronger. Perhaps even enough to confess his love!
