In some worlds, there are some beings called female supporting characters. Their endings are tragic and full of resentment...
The time and space exchange, which is independent of the three thousand worlds, reached a deal with them, using the energy brought by their powerful telepathy in exchange to realize their wishes.
Rule 1: Ensure the normal operation of the original world and do not harm the hero or heroine
Rule 2: If the host behaves in violation of Rule 1, the system can forcibly stop it.
Rule 3: In case of special circumstances, Rule 1 shall prevail.
Ps: The protagonist of each world is the original female supporting role. The system only plays a supporting role and is responsible for collecting energy to provide help.
World 1: The irritable and reborn princess with max strength vs. The subjugated princess who endures humiliation and bears the burden but looks weak and subjugated
World 2: After rebirth, the school girl who is bent on revenge against the male protagonist vs. The gentle school girl who just seems inaccessible
Purpose: Cherish life
