I was reborn in a parallel world and returned to my high school days. I originally wanted to live a peaceful life, but the bad actors became popular with "Blue and White Porcelain", and my scumbag classmates inexplicably embarked on the road to technological supremacy.

"On what to do if my world has become a sieve", a harmonious city for you, me and him, and millions of happy families!
