I just thought of a line of dialogue.
"Since you love to play so much, let's play big."
"Okay, what to play?"
"... Look, how about getting married?"
Hence this story and this game.
I originally wanted to keep the story simple, but once the game started, everything became so interesting.
Hahaha, I am that Gu Xiaoxian who is hard-working, positive and persistent, who can flirt with girls even when he is up or down. And Gu Xiaoxian is not Xian'er.
