TW: dub-con, sadomasochism, exhibitionism, erotic humiliation, urination, etc. --- There is a summary of the first chapter in the main work. You can read chapter 1 in Japanese here (no English TL yet): https://bato.to/title/145822<hr> The main focus of this chapter is Kenji's jealousy-fuelled sex, followed by a happy ending! The protagonist, Hinako (aka Kuro), became Kenji's lover after being trained to become his pet dog. She spends her blissful days with him, who's kind and sweet, yet still yearns for the days when she was his submissive dog. "Once you've become a pet dog and tasted the pleasure of being one, your body will never return." Even though Hinako wants to be retrained by Kenji, she's afraid of losing her happiness. While hiding her desires and letting the flames of passion simmer within her, Hinako's co-worker approached her and wanted to talk to her personally when something occurred... Kenji, seeing Hinako with another man, cannot hide his jealousy and decides to retrain her to remind her who her Master is...<br><br> Characters: * [Hinako Kuroda (aka Kuro)]: In the previous chapter, she suddenly appeared in front of her neighbor and crush, Kenji, and wore nothing but her underwear, dog ears, and a collar. After seven days of training, she became his lover. Hinako loves Kenji very much. She enjoys the sweet and lovey-dovey sex with him, but her masochistic side might say otherwise. * [Kenji Sudou]: Hinako's neighbor and boyfriend. His sexual preferences used to be normal, but thanks to Hinako (or rather, Kuro), his inner sadism blossomed. He loves Hinako very much and cherishes her through gentle sex. However, he can't control himself when he sees Hinako being close to another man. * [Miki]: Hinako's co-worker. He's friendly with Hinako at work and tends to be unreserved around her, but he's not a bad guy. * [The twin sisters Mai and Maruka]: Hinako met them during her 7-day training. They're also submissive, masochistic dogs who are adopted by the owner of an SM club, from whom Kenji seeks advice.
