In the 125th sentence of Huo Ying, I love Luo. Why did he say that he owed a great favor?

Because I fought Naruto in the exam, Naruto lit up my love for Luo and pulled him back from the dark abyss. That's why I love Luo to give up my past self, start to cherish my friends, cherish myself and others, and find the value and significance of my life. Therefore, I owe Konoha a favor, which is actually to thank Naruto.
