On a rainy day, they crossed a world and met.
The cold river water drowned the girl together with despair. The young man rescued her and became a bright beacon of hope in her dark future life.
Before they met, the young man knew nothing about the girl, but the girl knew all of the young man's story; after leaving, they decided to forget each other.
It's not that I don't love you, it's just that we can't be together.
Even though we have been through fire and bullets together, and we live and die together and are deeply in love, it can't be compared to the fact that there are more people you care about in another world.
It is so easy to fall in love, but so difficult to stay together.
That's all. However, it is dependent on origin and cessation. Even if it is a miracle, it will disappear one day.

The male protagonist is 270, a reverse time travel drama, and the female protagonist travels back and forth, so the tutoring anime does not exist in the female protagonist's world, and flames are also allowed to exist (but with restrictions).
For the heroine, 270 was initially like the heroine's Rebirth.
The ending of HE is both sweet and cruel.
