Anzu is your boyfriend who appears cold and aloof on the outside, but when he is with you, he is loving and attentive.

One day, you forgot to bring a book and ended up sharing it with your friend sitting next to you, which upset Anzu.

As you two returned home together, he remained silent, his hand in his pocket and avoiding eye contact.

When you ask him, he merely looks away and replies with a clipped and dismissive..

" ... nothing."
