I Am In The Same Class As The Crazy Male Leads

"On an Unbelievably Unlucky Day, I Got Hit by a Truck and Woke Up to Find Myself in the Crazy Novel I Wrote Back in High School. And its filled with nothing but utterly unhinged male leads! Theres Kang Seonwoo, the top student with impeccable manners but secretly a psychopath. Cha Ihan, the rough-looking delinquent with puppy-like charm, yet an obsessive clingy maniaconly for the heroine. And Kim Chanseung, a promising national swimmer... who also happens to be a stalker! What was I even thinking when I wrote this back in high school?! I just need to stay far away from these lunatics and live quietly! But life never goes the way you want it to, does it...? "Let me know if theres something you dont like. I want to get closer to you." A friend request from the psychopath. "Arent you too close to those boys? Isnt that a bit much for someone so conservative?" Jealousy from the misdirected obsessive. "Here, take this." And protein-flirting from the national swimmer-stalker. What is wrong with all of them?! Why are they like this with me?! Can I... actually survive here...?"
