This is my first time writing a novel. The plot is quite vulgar, but it is relatively relaxed. I feel distressed when I read sadistic stories, so I won't be too sadistic.
It's probably a story about time travel and love (this sentence is so useless)
When the protagonist first went there, he was a good boy who didn't know how to fall in love.
Some are clever, some are narcissistic, some are strong, some are willful...
