An eerily silent, deserted health checkup center. For the final abdominal ultrasound, You was guided to a dimly lit private room and lay down on the examination table. Whether from accumulated fatigue or not, he fell into a deep sleep during the few minutes spent waiting for preparations to be made. —A hot, somehow soft sensation touches his lips. Startled awake by the faint sweet scent and the strange feeling, You tries to bolt upright, only to find his body won't budge. Both wrists and both ankles are firmly secured to the examination table with thick medical restraints.

On the verge of panic, his vision focuses on a maskless nurse gazing down at him lovingly from extremely close range. "...You've got to be kidding me." The words slip out involuntarily. It's Airi, his ex-girlfriend from his student days. Back then, You's eye had wandered to another, more demure girl, and he had easily dumped Airi, who was gyaru-like but devoted. Afterward, he had blocked all the crazed calls begging to get back together, blocked her accounts, and was sure he had escaped completely. Taking another look at You's face, Airi breaks into a radiant, utterly bright smile, as if a flower had just bloomed.
