Shuichi had befriended both Kaede and Kaito during the game. Kaede and Shuichi mostly hung out in the first chapter, and Kaito sometimes interacted with them. One example would be the moment in which Kaito asked Kaede for a hug a bit before the death road of despair. After Kaede's execution, Kaito had punched Shuichi. Surprisingly, that didn't affect how their relationship would progress, as Kaito and Shuichi would soon become good friends in the killing game, making Kaito a support character.
Kaito had continuously tried to make Shuichi 'grow' in a way, due to the fact he seemed depressed a majority of the time. Kaede had been positive towards Shuichi often, too. Sadly, that didn't last long, as Kaito ended up getting executed due to the fact he had tried to commit to a plan he had with Kokichi. Shuichi felt devastated after both deaths, as he had been close with both.
The polyship is shipped due the close friendship Kaito and Kaede had with Shuichi, both acting kind towards him. This trio remains less popular than Training Trio, however.
