Seiji got cornered, and fell into her trap, when he attacked, he surprised her at first because he did it so fast, then she started to get boulder, because she had been attacking him for so long without getting a response at school, she got carried away, and forgot her breaks(wwwwwww), she might regret it but Seiji will definitely be regretting her getting carried away, he won't know what happened or how to deal with her (wwww), even if he had something he could do.

ちょっと正座して傍観してますね？(ﾟДﾟ)

風見さん意地になってますよね……（笑）
