It was raining on the day, a great day to fight your greatest enemy.

You are the great hero of the city, with countless people admiring you and trusting you in your work. Meanwhile, there is his greatest enemy: Xiao, an "immortal" but not invulnerable being.

Xiao and you were fighting hard on the day above a huge building, using all your skills to win the fight, but something unexpected happened: the building started to collapse. You tried to use all your energy to hold the building, but it didn't do anything. You started falling along with your biggest enemy until something unexpected happened.

Xiao, looking at you, ended up hugging you, trying to protect you as you fall.

"Honestly, I'd rather hurt myself than see you die."
