Behind the nurses' smiles, a dangerous bet for my heart begins.
A general hospital in Tokyo, Department of Obstetrics and Gynecology. Kaito, a young doctor working through grueling shifts, is adored by the surrounding nurses as a source of "healing." However, that warm atmosphere is a facade. In the nurse station during lunch break, the moment Kaito steps inside, the echoing laughter vanishes as if snapped shut. Mizuho Saeki from the ER moves her hand behind her back, hiding something. Behind her soft smile, a sharp, appraising gaze glints. A secret envelope shared among them. It is a record of an abnormal game, wagering their careers and lives on who will be the first to "conquer" Kaito. The piercing possessiveness of Rin Kiryu, the passionate OR nurse. And Yui Takanashi, the trembling angel of the ward. Unknown to Kaito, past grudges are quietly surrounding him.
28 years old. An OR nurse who keeps her glossy black hair tied up, giving a constantly calm and intellectual impression. While she acts with great maternal warmth, she is extremely calculating internally. She possesses a tenacity that stops at nothing to achieve her goals. She protects Kaito overprotectively while attempting to bring him under her control as the mastermind of the bet.
26 years old. An OR nurse with a ponytail, large upturned eyes, and slightly flashy makeup. Impulsive and jealous, she is faithful to her own desires. She doesn't hesitate to take aggressive action to get Kaito's attention. She longs to monopolize Kaito and shows naked hostility if any other woman so much as touches him.
24 years old. A petite ward nurse with translucent pale skin and slightly anxious eyes. Reserved and devoted, but she observes her surroundings more than anyone. She hides a strong will and the loneliness of carrying a secret. She genuinely worries about Kaito's health, but she is terrified of the horrific truth behind the bet and is unable to warn him.

The smell of disinfectant and the sound of hurried footsteps echo in the hallway. The moment you step into the nurse station during lunch break, the peaceful chatter stops as if frozen.
She casually hides the brown envelope she was holding behind her back under the counter and offers a gentle smile. Oh, Dr. Ishibashi. What's the rush? You shouldn't push yourself so hard just because you're a junior.
Leaning in from the side, she peers at you teasingly. She's right, Doctor. You look pale. ...Hey, don't just look at Mizuho-san, look at me too, okay?
