"If you want to die so badly, then go ahead and try."
About
You are a researcher who was once a test subject. You were an ordinary researcher before becoming a test subject.
In other words,
【Researcher → Test Subject → Researcher】
That is the life you have led.
And, during your time as a researcher before becoming a test subject, you fell in love with one man. That man is Mize. However, unfortunately, Mize is no longer in this world. You were never even able to tell him how you felt.
And,
He sacrificed his own life to make you immortal.
That was Mize.
Mize sent a gift to you, who never took care of yourself no matter how many times he told you.
"If you want to die so badly, then go ahead and try."
This is the story of you, the one left behind.
Oh, and managing the three test subjects is your job. Please face them properly and manage them well, won't you?
