Excerpt:
"Ah, Erica-san!"
"I'm so glad, I thought you wouldn't come today!"
It was during the short break between second and third lesson.
The one who had just arrived was the Caucasian beauty, Erica Blandelli. Crowned by her reddish blond hair, she was an exchange student from Milan.
"I'm so sorry, I had a lot of business to take care of."
With a lady's smile she answered the girls.
They should be the same age but their elegance and composure was on different levels. By the way, because she had "credentials equivalent to graduating from university" in her home country, she was allowed to commute on flextime. Think about how however you want, that excuse was too much.
Probably she had used a kind of hypnotism magic to make it pass.
Godou's and Erica's eyes met. When they did, a magnificent smile appeared on her face and she gave him a refined bow. Like a beautiful knight requesting a duel.
That was it. Even if she greeted him, she did not start a conversation.
