My Black-Hearted Roommate Caused Me a Tragic Death, and I Slapped Me Hard in the Face After I Was Reborn.

When my friends went to college, they still made the same demands on me as they did in high school. When I was registering for Level 4, my friend told me that I couldn't use my mobile phone in class, so he grabbed my phone and made me miss the opportunity to register. But she found someone to sign up secretly in advance. I wanted to participate in competitions, but she advised me to just study hard and complete my classes in college. She canceled my registration, but entered and won the prize herself. I couldn't find a job after graduation, and she got an offer from my dream company. I was desperate and borrowed money from her, but she righteously accused me, "I have helped you for so many years, but you continue to suck my blood." I died in an accident in a small factory. When I opened my eyes again, I was back to the day when school first started.
