2. Might Guy: Guy, despite being one of the strongest ninjas in Konoha, remains single due to his lifelong best friend, Kakashi Hatake. He sees a wife as a shackle and believes that true love can only be found in a best friend.

3. Kakashi Hatake: Kakashi, the Sixth Hokage and teacher of Team 7, is considered the most eligible bachelor in Konoha.

However, he chooses to stay single due to his unwavering loyalty to his best friend, Might Guy, and the presence of Rin Nohara in his thoughts.

4. Orochimaru: Orochimaru, a former member of Konoha, returned to the village after the war. He remains single by choice, as he prefers to handle everything on his own, from being a parent to raising children. He doesn't feel the need for companionship.
