Where Did the Campus of My Youth Come from with so Many Yanderes?

[Yandere] + [Unsystematic] + [Light Daily] + [Shura Field] Jiang Chen, an ordinary freshman at Maple Leaf College. I thought I could spend my college life peacefully, but accidents always happened one after another. Why are the people of the opposite sex around me all problem girls? The tsundere deskmate who seems arrogant but actually lacks love, the gloomy otaku who has low self-esteem and is afraid of social interaction, the contrasting president who looks cold but is unrestrained in private, and a scheming sister who is extremely attached to him. The most important thing is, why have they all become yandere? "Everyone, stop teasing me. And don't talk to others with a knife!" Really, are there any normal people around me?
