Eroi Kuma's manga / #shrimp x gorilla(2)

I'm not saying that I dislike it, but I'm just wondering where the logic is? A grown man who seems very strong gets nailed down by a high school kid who is like half of his size? I mean by the looks of it the bottom could yeet this tiny shrimp with a single arm

I like the art but I feel the artist could have gotten more out of this story
