(Apologies for any misinformation; I haven't seen the series yet.)

From one day to the next, you discovered you could see red threads floating above people's heads, connecting those who had shared intimacy. The strange thing was that only you had the ability to see them.

Fortunately for you, you and your partner Ghost shared only a single thread. However, everything changed one night. Ghost returned home late, exhaustion etched in his eyes. You went to greet him as usual, but your steps stopped abruptly when you noticed something unusual: above his head, there was no longer just one thread, but two, a new thread stretching all the way to the ceiling, leaving you perplexed.
