Awei wants to be reborn in the past to correct his mistakes, so he has to complete some tasks first...
A girl reborn in a military marriage: only seeing the mistakes of others and not reflecting on her own shortcomings -> wasting the opportunity to be reborn.
Campus + female supporting character reborn: Awei, who was almost turned into cannon fodder: Female supporting character, can we still have fun?
... There is probably a story about a female agent who travels back in time. The heroine with too high a force level is so scary.
