Things i understand : Mochida is a bitch and Sei has going to Mei Aihara's school on how to deal with blackmail by almost kissing Mochida like Mei has kissed Matsuri. Also Mochida is totally delusional about not wanting to be Maths Teacher GF,you totally want it girl, just admit it and it will be better.
Thing i don't understand : Is Haruka still not over it ? I thought the point of last chapter was that she is over it. Did i misunderstand her reaction here ? Can someone explain what she mean about Aya not being angry about what happen ? Is she talking about last chapter or something else ?
