As Yu Chen and Hiromi Jounouchi discussed coming back early from their honeymoon, Miketsu and the Matchmaking God arrived at Minami's family's small shop, accompanied by Suzuhime.
Although they were aware that every move Minami made was under surveillance by the Metropolitan Police Department and the Public Security Intelligence Agency, and so far she hadn't shown any intention of contacting Inomata Naoki, Miketsu understood more than anyone else what the Matchmaking God meant by bonding of fate.
There is a Red String of Fate connecting each person with their predestined partner, invisible until the destined time. And when fate arrives, the string becomes visible.
The process where the invisible becomes visible is what the Matchmaking God referred to as "tying the knot."
