Yeah. I'm squarely of the opinion now that the Teacher likes having the head of a young boy between her thighs (sniffing her crotch and getting a boner) pretending to crush it. She is actually the BIGGEST pervert in this whole manga. I guess she likes to tease so she won't take it TOO far right? ... RIGHT? LOL.
@Kefkabot Idk I wasn't the one who added those. I guess someone interpreted it as such considering the relationships between Daichi+Akari/Kaguya-sensei and Kaguya-sensei+Kumagaya/Daichi/Akatsuki-senpai but calling it a harem is definitely an overstatement. Think there are other characters that get added into the mix later on but I haven't read that far.
