"I never knew a tough-looking Omega could be so sexy and cute as a lover!!!" Kota, a university student with the unique Alpha trait, has a boyfriend named Ryunosuke, who is tough, beautiful, and sexy. Even though taking good care of Ryunosuke is his top priority, she keeps showing him her nape and teasing him by saying, "Just bite it!" Kota declares that he doesn't want to bite Ryunosuke, but while he's away from him, he falls ill -- and in a daze, when Ryunosuke returns home, he tries to bite his nape, saying, "I can't do this anymore" --!?!?!?!?!?!?
