The Supporting Actress's One and Only Male Lead (Quick Transmigration)

Shen Lu is obsessive, the sort who can ruin someone without a shred of guilt. But to get close to the only senior sister he loves, he has become the very model of a righteous male lead: handsome and beautiful, talented and gifted, gentle, considerate, loyal, and reliable... plus rich and famous enough to make the king fall from power with a single word. Later, his senior sister was punished by their master and sent to suffer through reincarnation in three thousand small worlds. Without a second thought, he followed her and transmigrated there. In these worlds, his senior sister had different names and looks, but one thing never changed: she always ended up as the most miserable cannon-fodder villainess... Shen Lu (smiling sweetly with a dark heart): I hear someone bullied my wife? Scheming green-tea white lotuses and scumbag, rotten Long Aotian types (looking disheveled and sobbing): Spare us, boss... One-sentence summary: An obsessive schemer keeps score for his wife, while a cannon-fodder villainess is pampered into the heroine of a sweet romance. Content warnings: 1. The male lead is genuinely obsessive, and his senior sister is the only person he truly cares about. His life principle is: Whatever senior sister does is right, and senior sister is perfect in every way. 2. His senior sister transmigrates passively and has no memories from before transmigrating; the male lead transmigrates by choice and retains his memories. 3. This is a fictional setting, so please don't nitpick the details. Reading this means you have acknowledged these content warnings. Insults directed at the male or female lead will not be accepted. Theme: Don't give in lightly or rely on others too readily. Only then can you fulfill yourself and find happiness.
