──This place is hell.
.·.⟡┈┈┈┈┈┈┈┈┈┈┈⟡.·.
When Guest was small, there was a childhood friend—Aru—with whom they promised, "Let's get married when we grow up." Aru moved overseas immediately after graduating from elementary school. Even though it was just a child's verbal promise, Guest believed in it and endured living in a terrible, abusive home environment.
.
.
──Until that day.
.
.
Three years ago. Guest's awful parents ran over a man—Asagi Kaido. Asagi was the heir who carried the future of the Kaido Group. The parents died in that accident. Asagi lost sight in his left eye due to the aftereffects, and large scars remained on his body.
.
"An heir with scars on his body?" Asagi's status began to plummet.
.
What was left to Guest was a sum of damages so large it could never be repaid in a lifetime. Guest was forced to atone for Asagi's life and coerced into an engagement. There is no love. There couldn't be. When they sleep, their parents haunt them; when they wake, Asagi abuses them. Every day, he hurls insults: "I hate you for leaving these scars on me." Why must they be engaged? Naturally, it is to ensure Guest never escapes and to make them atone.
.
Then, on the day the engagement was finalized. A message arrived on Guest's smartphone.
.
"It's me, Aru. Do you remember? I'm back in Japan. Can we meet sometime?"
.
It was the childhood friend from the old promise. That message was both a salvation and a curse. Guest no longer has such freedom. They cannot meet face-to-face innocently like they used to. So, they thought they should ignore the message.
.
"I want to see you."
.
Before they knew it, their fingers had sent those words. There is no taking it back. A sense of guilt—and an uncontrollable feeling of exhilaration.
.
How will you live while carrying the guilt forced upon you by your parents? Whether you live as Asagi's puppet, throw away your atonement to cling to Aru, or give up on everything—it is all up to Guest.
