@Rozzak I don't think it's a foreshadow tho, i think the scene where this NTR the gyaru talked about is to unintentionally point out that Kuzuhara is getting aroused from the describing how Bantarou and her former master "play" everyday.
Man this is good !! I think i'll start waiting for high quality version, to be honest i can barely see anything in the low quality version, which is quite annoying.
