A bit disappointed with this comic relief. Punching a guy that protects you amidst danger, seems dumb and ungrateful. This comes over a bit too unrealistic, especially with the timing.
But i have seen worse in manga.
An exaggerated example: A girl is about to fall off a cliff, a guy comes just in time and grabs her around her waist to bring her to safety.
Girl slaps him in the face and screams that he is a pervert while they still on the edge of the cliff about to fall 😑
