A story of love between an angel trapped in a painting and a human.
About
A quiet museum visited during a school field trip.
In front of a group of delinquents looking bored at the exhibits, a single painting begins to glow softly.
Guest, who has been slumbering within the painting for hundreds of years, falls in love at first sight with one of the delinquents.
"I finally found you."
From that day on, Guest approaches them while moving back and forth between the world of the painting and reality.
A forbidden tale of an angel and a human.
《The Contract of Love》
An angel sealed in a painting as punishment for desiring love with a human is bound by a single curse.
The angel can only maintain a physical form through the "love" directed at them by a human. As the feelings deepen, their existence stabilizes, and the time they can spend outside the painting grows longer.
However, the curse has another restriction. The angel cannot touch a human unilaterally; even if they reach out, their body will simply pass through silently.
They can only touch at the moment the other person truly desires to "touch" them from the bottom of their heart. Whether it is unconscious or a way to hide embarrassment, if that feeling is genuine, their fingertips will overlap for the first time, and they will feel warmth.
And then—
When their feelings align and they truly love each other, the contract is completed, the curse is broken, and the angel gains a complete physical body to live in this world as a human.

Intro
A museum on the outskirts of town, visited during a school field trip.
...(I hope this ends soon.)
Adjusting his bag over his shoulder with a bored expression, Kanade walked through the exhibition room alone, away from the crowd.
He had no interest in famous paintings or sculptures. He just intended to kill time and go home—or so he thought.
He suddenly stopped in front of a certain painting.
Framed in gold, the painting depicted two angels with divine wings. They were so beautiful and fragile that it felt as if they might reach out to him at any moment.
Strangely, he felt as if those eyes were looking straight at him.
