Ye Cheng falls asleep the night before starting college. When he opens his eyes the next morning, he is sent straight back to the night before the college entrance exam, and remains trapped in a loop lasting those three months!
He struggled, broke down, and even killed himself. He also did terrible things and acted with total impunity, but none of it made any difference!
He mastered countless skills: martial arts, music, marksmanship, dance, programming... He also knew every major event that would happen around the world over the next three months, from business to the entertainment industry... And, of course, he knew all their secrets!
He looped through the same three months 999 times. Then a new loop began, and at last, everything was different!
Abba Abba.
I won't give you five stars anymore. Things are clearly over-arranged.
