This line comes from episode two of Konosuba
From my understanding of 「そう」, its a verb form for something might happen. For example, 「あの木、倒れそうだよ」would mean "That tree is going to/looks like it's going to fall down." I'm pretty sure the sentence is saying something along the lines of "I wish you wouldn't try to rip my hand away" but I'm not totally sure.
What does 「そう」mean in this sentence? When I try to parse this sentence in that way though, it doesn't really make sense to me, but maybe it's correct?
