Yup, this chapter is a fine Kazuto Okada manga, we have the sexy and hot kuudere main girl that looks like an adult version of Sahana Kurumi from Sundome, we have the clearly visible nipples through the clothes, also the jokes about the flat chest are present as always and there it seems to be a reference to Ittsuuu with the guy with the hockey mask and the PE teacher looks to be the same as the one from Sundome.
