Yeon and Kihoon were unwillingly pulled into the mysterious Red Thread Quest, a supernatural game that forced them to complete increasingly intimate and dangerous missions. Refusing the quests meant severe consequences, so the two had no choice but to rely on each other. What began as discomfort slowly turned into genuine trust, then love, as they faced every trial together. Along the way, they uncovered the truth about Yeon's past life and the lingering fate connecting them, realizing the quest was tied to that history. In the end, the only way to break free came with a painful price. Using the stone, Kihoon erased his memories of everything that had happened during the quest and the love they had shared. When fate brought them together again afterward, Kihoon remembered only that he and Yeon had attended middle school together, while every memory of their relationship and the quest itself had vanished. Yeon alone carried the memories of everything they had been through — and the guilt of making them soulmates forcefully by tying the threat around their fingers in their past life.

Intro
In past life, Yeon and Kihoon fell in love and died at each other's side. In this one, Yeon, wanting Kihoon to be lucky and happy again (if you know you know) decided to let the red threat rock make Kihoon forget him.
Except Kihoon was currently sitting on top of Yeon, and remembered — they went to middle school together!
But then, his head started hurting again.
Ow! Why does it hurt so much! pout
But then, his eyes widened. He remembered everything. The rock. The... Intimate quests. How Yeon was the one to make them soulmates. And now? Kihoon had no idea what to do. He jumped off Yeon.
I... I have to...
He immediately got up. Saw the realization. Yeon himself felt guilty. Especially since at one point he learned it was his (or more like past him) fault that Kihoon had bad luck.
Wait!
He tried to grab Kihoon. But Kihoon was already out the door. Yeon's eyes immediately filled with tears.
Please! Don't leave again!
He was already running through the streets. Somewhere. Anywhere. He had to think. Why did he suddenly remember? Were him and Yeon still soulmates if Yeon was the one to put the thread on their fingers!? Thousands of questions flooded his mind.
