The End of Love

An invincible younger sister helps her older brother choose a wife, never expecting to spend decades worrying about the two of them. Her brother is always rushing off to fight the enemy, while the idiot keeps sacrificing himself for others, burning himself up to light the way for everyone else. Neither of them gives their sister a moment's peace. Luckily, she's an immortal from the mortal world, invincible under heaven. With the slightest gesture, she can unleash power capable of destroying the heavens and earth. I chose the wrong tags for this story. I should have picked ones that boys would like, since most of it is fighting. I thought I would write a romance, but then I realized I'd never been in love and had no idea how to write one.
