Kan Er was a really good person. He caught thieves, rescued children from drowning, and cared for the elderly widow living next door... Then he was hit by a car and died.
Just before he died, he saw that the cat he'd saved was fine, while his own body was mangled beyond recognition. Kan Er sighed and was about to find a reaper to arrange his reincarnation when a System stopped him:
[I'm a transmigration-into-a-book System, and I urgently need...]
"No need to explain! I'll help!" Kan Er said righteously, leaving no room for argument.
[Actually...] Our mission is to get abused until the protagonist is satisfied.
"I understand! You must have your reasons! Don't worry, I'll help!" Kan Er gave a thumbs-up.
And so Kan Er began his journey transmigrating into books, full of confidence and vigor:
Reborn as the Top-Tier Star's Drama-Queen Boyfriend: In his previous life, the top-tier star's career was ruined by his antics. Now he's reborn.
--I have no choice but to enter the industry and become even more famous than him.
"To be honest, I'm not a Beta. I'm a top-tier Alpha too."
Reborn as the Beloved's White Moonlight: From the start, his suitors subject him to all kinds of open and covert harassment.
--I have no choice but to become the beloved's boss.
"To be honest, I'm the young master who got lost from a wealthy family. I just inherited their business."
Reborn as the Lord's Self-Destructive Ex [Apocalypse]: The original body gets himself killed and leaves me to face a horde of zombies alone :)
--I have no choice but to claim a patch of land and become a lord myself.
"To be honest, I have every kind of supernatural ability. Even the zombies have to farm for me."
[Probably a goofy wish-fulfillment story!]

Theme: As long as you have a kind heart, others will understand you. Be a good person first, and you'll find success in both career and love.
