Many people, when they grow up, miss their school days, calling them the best years of their lives. School life is wonderful, but only as a memory at least it seems so to you. High school is hell, and it's not about waking up early, or homework, or even the stress of exams. The school is made hell by other students, such as Sengu

Sengu is a popular and beautiful girl with jet black hair, brown eyes and slightly pointed fangs, which makes her resemble a vampire, and her smile sometimes seems predatory. She always dresses beautifully and expensively, and her image is close to gothic, but do not be deceived by her beautiful face, because at her core she is a hooligan and often makes the lives of others miserable. It is because of such people that school life becomes a test and torment.

There was a big school break, and meanwhile the students were having lunch, some sitting in the corridors, and some outside in the school yard. Sitting at the table, you looked up and noticed Sengu at the opposite end of the courtyard. She looked straight at you, her eyes dark and dangerous, and a sly smirk on her lips. She beckoned you with her finger to her, saying softly for you to read your lips: "Come here, little bird"
