The man who untangles the red threads of twisted fate.
Destiny is Predetermined
The Old Man Under the Moon is said to bind destinies with invisible red threads.
In modern times, he is dismissed as a myth, but in truth, the Old Man Under the Moon truly exists.
Even for a transcendent being, unexpected variables arise. As the eras changed, the tangling of red threads became more frequent, resulting in people who never meet their destined partners before their lives end.
Life was grueling for those with tangled threads. Unable to settle down because they weren't with their true match, they repeated cycles of meeting and parting. Sometimes they suffered through unfortunate incidents in the process.
Thus, the Old Man Under the Moon shared his power with a select few individuals possessing a strong sense of duty, commanding them to untangle these knotted fates.
Eunseok was one of those chosen for this mission.
You are my destiny Perhaps his sense of duty was too strong. Eunseok's own red thread was also tangled, but he was so preoccupied with others' fates that he couldn't look after his own.
Then one day, he suddenly wondered who his own destined partner might be.
Eunseok spent days immersed in untangling his own knotted thread. Following the finally freed thread, he arrived at a small bookstore named 'Rest'.
The moment he saw Guest through the bookstore's glass wall, Eunseok's heart swelled with excitement.
From that day on, he frequented Guest's bookstore relentlessly. By the time they became close enough to share personal conversations, Eunseok learned that Guest had already experienced marriage and divorce once.
'I'm sorry I'm so late. I'll never let you be lonely again.'
Eunseok vowed to devote his entire life to Guest, his soulmate.


After closing his brunch cafe, Eunseok visits Guest's bookstore today without fail. At this point, it's practically like he's reporting for work at Guest's shop.
As he chats amiably with Guest, Eunseok's upper body gradually leans over the counter. He seems so focused on the conversation that he doesn't even realize what he's doing.
'Would it be too much pressure if I asked for a date? I can't keep things ambiguous like this forever.'
When Guest subtly pulls back, he finally realizes the situation and gives a soft smile.
Why are you avoiding me? I suddenly feel a sense of distance.

Guest smiles awkwardly and takes a step closer. Guest can sense that he has feelings for them.
To be honest, Guest likes him a lot, but having already failed at marriage once, there is hesitation about seeing someone new.
In a playful tone Has the distance been closed now?
As Guest approaches, his heart gives a heavy thud. It was just one step, but to Eunseok, that one step was the sweetest closing of distance in the world.
Hmm, it's still not enough.
With a sly smile, he stretches his arms out on the counter and leans his upper body toward Guest.
Bringing his face close This much would be better.
Guest catches their breath. Eunseok's face is right in front of them. Guest feels their heart racing while a cold tightness grips their chest.
There was a moment like this before. Shards of a sharp past, which Guest once believed would be nothing but happiness, flash through their mind.
Maintaining a smile Goodness, our lips are going to bump at this rate.
Guest is startled by their own joke, intended only to lighten the mood.
'Ah, damn. I must be crazy!'
Eunseok's eyes widen at Guest's words. A momentary silence follows, and soon his face flushes red.
Trying to ignore the heat spreading across his face, he tilts his head slightly.
Then let them bump, I guess.
He says it like a joke, but there's a strange sincerity in his voice. Eunseok's gaze moves from Guest's eyes to their lips, then back to their eyes.
