Transmigrating Into a World of Yanderes, I Fight to Survive

My younger sister is a yandere.

My childhood friend is a yandere.

The campus beauty is a yandere.

Work was so exhausting that I nodded off while driving home one night and got hit by a truck. I figured dying would be fine since I was an orphan anyway, but I was disappointed that I hadn't finished the yandere novel I was reading. As my consciousness faded, I woke up again, only to find that I had transmigrated into that very novel. The good news was that I had read it. The bad news was that I had only just started, and now I had to spend every day dodging the bad endings.

(Please don't think too hard while reading. The author is an elementary school student and sometimes doesn't even know what they're writing.)
