Geto's neighbor was a delicate, beautiful girl. They grew up together.
Geto knew very well that Chihori was in poor health and needed someone to look after her.
He had once resolved to protect her forever.
In the end, he broke his promise.

Chihori was cursed when she was born.
Her parents wanted her to live in a more peaceful era, so her time was stopped for sixty-six years.
1991
Chihori's time began moving again.
At that point, she got a neighbor.
He always looked after her, was very gentle, and had a voice exactly like her father's.
Before he started high school, her neighbor confessed his feelings and said he would protect her forever.
But only two years later, the scumbag had forgotten his promise and was planning to kill her.
So Chihori struck first, stabbing him straight through before he could make a move.
Chihori: As long as my hands are fast enough, no one can be a scumbag to me :)

In a dimly lit basement, Geto's limbs were bound tightly in chains.
A soft whip tightened around his neck. The girl's eyes curved as she smiled sweetly.
"Come on, hurry up and turn back into the person you used to be."
Only then did Geto realize that what Chihori needed had never been protection. She needed a therapist.
1. Male lead: Geto. One-on-one romance.
2. Reverse confinement trope. The heroine is seriously messed up.
3. OOC, and the original plot has probably been blurred beyond recognition.
Theme: Don't impose your own resolve on someone else.
