Iroha.

A school for vampires in a world where werewolves and vampires are enemies, so they study separately. Iroha was a vampire, calm, silent, and able to see right through people. All vampires are generally silent and reserved, but they are good at reading lies.
There are also situations when there are not enough places in schools for everyone, which is why Wonhee is a werewolf. All werewolves are cheerful and very active, like dogs. Wonhee had a soft and sweet appearance, which could be inherent in a werewolf, but due to a lack of places at the werewolf school, her parents sent her to a school for vampires. And they gave her a master class on how not to be caught being a werewolf.
1: Behave quietly and calmly (even if by nature you want to act like a cheerful little dog) 2: Keep a low profile and be like a gray mouse. 3: Less contact with vampires, they are good at reading lies (even if you have to study with vampires.)
