Back Roomthe Meaning of My Existence

Xiaotang, a junior high school student, has pink hair and black eyes, and is 155cm tall. But I like things that are a bit scary and cute, so I became obsessed with the back room. Unexpectedly, when I was sitting in the classroom and brain-smoothing math problems, I time-traveled as soon as I closed my eyes. Just time-travel. I found a bottle of blueberry juice in the Manila room. I thought it was a resource supply, but it turned out to be a bummer after a day of pain, but you can switch at will. So, Xiaotang embarked on a journey with the belief that his kind would not become extinct... (The protagonist is not invincible, or even weak, but his spiritual character is an advantage and his appearance is cute)
