I feel that Shiro has always regarded Zabuza as everything to him, even sacrificing himself to protect Zabuza. At the same time, Zabuza also regards Haku as a part of his life, but the way Zabuza cares about Haku is a bit special. Secondly, because of Kirikage's environment, Zabuza can only keep hinting to himself, I am a ninja, and ninjas are tools. Can't have feelings. We have always cared about the people around us, but sometimes we don’t even realize it. Because we care, we will subconsciously do things to care about others. Shiro sacrificed himself to protect Zabuza, and similarly, Zabuza also used his own life to protect Shiro's dignity.

2. Itachi and Sasuke

"No matter what path you take in the future, I will always love you deeply." ------ Uchiha Itachi.

Sasuke has always felt that no one loves him, and no matter how hard he tries, he can't keep up with his brother. My father always only has eyes for the genius of his brother, and he never gives himself a compliment. And the elder brother never failed to take the agreement with him to heart. He would only say "next time, Sasuke" every time, and even tortured himself in that way after killing the entire clan.

But he didn’t know that his father, who didn’t love him, wanted Itachi to take care of him in his last words before he died. He didn't know what price his most hated brother had to sacrifice to protect him.

Uchiha Itachi, the hero of Konoha, is also the sinner of the family. For the sake of the village, he sacrificed his entire family and helped end the war after his death. He was reincarnated in the dirt. For the sake of his brother and the village, he would rather bear the guilt of his whole life and choose to be the darkness that sets off the light.

How much pain did he endure after killing his tribesmen and torturing his younger brother? He was misunderstood and slandered, but he never complained. For the sake of his young brother and the peace of the village, he voluntarily put on the disguise of a rebellious ninja and became a person who was completely unlike himself. "Love is restraint." If you don't watch Naruto, you will never know how heartbreaking his tears were that night.

3. Jiraiya and Tsunade

"I always lose in every bet, so I bet that you won't come back. But unexpectedly, I won the last thing I wanted in my life." A winning bet. "-----Tsunade.

When Jiraiya said goodbye to Tsunade, I believe many friends shed tears. Jiraiya has been in love with Tsunade his whole life, even though Jiraiya said that happiness is not something that men should pursue. But what he said to Tsunade before leaving, Jiraiya still hopes to come back and pursue his happiness. When Jiraiya said goodbye, he said "じゃね( Kano)" instead of "さようなら(sayunara)". The former means to say goodbye casually and see you again in the future. The latter expresses farewell. Jiraiya probably said this to reassure Tsunade. That friendship is in my heart, how can I say goodbye forever.

Tsunade also has the same feelings for Jiraiya. When Jiraiya said goodbye, Tsunade blushed. From this, it can be seen that Tsunade also has love for Jiraiya. of. But there is no chance to express this love again.
