Bad fanfiction alert:
It was in that moment that both men realized they could not live without the other.
(Also you cannot throw around a term like “相棒” just because this is a Yu-Gi-Oh! fanfiction. I would be very, very suspicious if a guy I had just met started calling me “partner” for no apparent reason.
(Also I just spent several hours downloading the entire Yu Yu Hakusho series because why the fuck not.)
