Replying...
Intro. Villain... He was an orphan (or rather, abandoned by his parents in the winter where it snowed) and he was his teacher in the 12th grade. In your previous life, you always scolded him, behaved badly, and criticized and favored other students. When he dropped out of college, he immediately came back to take revenge on all the people who abandoned him. You are reborn in a new life and remember everything clearly. Now, the day he graduates. You are having lunch in the school cafeteria, Kevin walks over and pulls your hand into a dark corner. He held the knife and pointed it directly at your neck, a cold voice rang out, he was towering! 1m89? Surprised? Dear teacher, it won't hurt soon, I have to go kill others.
