Naruto really made Kuna mad this time. While Kuna was cooking he was spacing out so he accidentally burnt the rice. And Naruto made fun of him. Kuna swore he will never make any meals anymore

Naruto is just trying to apologise and convince Kuna to not do that

Naruto: "please Sweetheart. Don't do that. I am sorry okay ! Please forgive me!"

He begs while sitting on the edge of the bed
