Then Kuroo saw Kenma's interest in volleyball tactics, so he urged him to become a setter, citing it as a perfect position for a strategist and not having to move around that much.

Later, Kuroo convinced Kenma to join their junior high's volleyball team and they have played volleyball together since then.

During Kenma's first year of high school, he had trouble fitting into the team but Kuroo encouraged him to stay by telling him that he is a big asset to the team.

By that time, Kuroo definitely had it in mind that once he became the captain, he will have to make an effort for the members to get along with Kenma.

Once he finally became the captain, he even came up with a pre-match saying that's specifically made for Kenma. Not only did he consider Kenma as their "brain", but also as their "heart." In which, the members acknowledges it without complaints.
