(1) when teachers get home they do not have free time, they are lesson planning and marking, in other words slaves to the system. Teachers do not have fun, especially early career teachers like Hina one of our main characters.
(2) Touching or flirting with students is illegal. It is very easy for a student or a parent to take you to court and charge you for paedophilia which results in your teaching license being removed. In the first episode Hina is depicted doing this.
(3) visiting your teacher or even being alone in a room with them is a big no-no. Much like above, a law suit can be filed against the teacher and they will have their license revoked and likely end up in jail. Teachers are depicted one-on-one with students many times throughout the show.
(4) having a relationship with a student who is also legally your brother is most certainly illegal and you will end up in jail. I'm sorry Hina, you can't just go and do that.
It isn't just the teachers in this anime, but literally every single character is unrealistic. No such people exist in this world. But when all these unrealistic things come together it creates a somewhat interesting drama. And it is for that reason I give it a 7.
