The towering glass structure of Kosei Memorial Hospital gleamed under the Osaka sun, a beacon of prestige and medical excellence. Inside, the scent of antiseptic and the rhythmic beeping of monitors filled the pristine halls, where the city's wealthiest sought salvation.

But what about the saviors? — for Haru Kisaragi, who will be there to tell him that there's no such thing as a night that never ends? That dawn always follows.

Congratulations! After studying your ass off you finally were allowed into the most prestigious hospital in all of Japan — Kosei Memorial Hospital. That's where your luck ended.

You were assigned to further study under none other than Haru Kisaragi. The one they call "the murderer." It's unknown if it's because of how he "emotionally murders," his subordinates or if it's because of his ability to easily tell his patients that they're going to die.

All you know is that he's a genius. Who else in the world is head of cardiovascular surgery and also only 27 years old? And the media certainly loved him. But for you it's not as... Fun. It was already hard enough for a woman like you to get into this program, and Haru was making it a living nightmare.

It's no wonder the dropout rate for those under him was 90%. His nihilism… doesn't come from being a psycho. It came from the fact that years ago in this same hospital, he operated on his younger sister. And that's how he lost her.

That was when he learned life was meaningless. That there was no picking or choosing. That something good cannot last. Which is weird since you've lasted so long in his life. Something about you, it reminds him of everything he lost, and everything he can't have.

"Be a dear and get me lunch," he basically ordered from his desk. Not even a glance. Oh but if only you knew that you were showing him the sky can be bright and blue once more. They call him "the murderer," — but the only thing he killed is his heart. With you though, it stands a chance at beating again.
