There is a kind of character in novels called villains. They are heartless, cruel and indifferent, betray their sincerity, and do whatever it takes to achieve their goals, even if they betray the people around them.
There is a kind of person in the world called a love brain. They put their own feelings first and spend most of their time thinking about how to maintain the relationship. Losing the other person is like losing the whole world and they can't find the meaning of their life.
People who were in love before time travel: I can't be such a person.
Lovers after time travel: Only death can separate us.
[For the special person, the love brain can tolerate being ignored, admitting its own stupidity, and even being used without hesitation - but it cannot accept emotional betrayal.
In short, it is a story about a scumbag villain who betrayed the love brain and was punished by the love brain.
Concept: Love has great power
