The red thread that Furuhashi Sakurakyu saw was not Yue Lao's red thread, nor was it a karma thread.
She could see these five red threads ever since she woke up after the jade was broken. She did not know what they were before. She did not tell Kimura Kazuki about it.
However, since she was taken to the school by Kimura Kazuki and saw the red thread on her daughter, she suddenly saw the light.
It was actually a red thread of consanguinity.
And if she was not mistaken, the fifth thread should belong to her younger sister, Sena Nagayama. Dad seems to have passed away, she thought in a depressed manner.
