The Star Pirate Insectoid's Rules of Romance

Synopsis: Wen Di unexpectedly showed a little kindness and saved a bug. The System prompted him: [Congratulations, Host! You've encountered a key character in the main plot!] Wen Di exploded on the spot. He'd been transmigrated here for twelve years and spent all twelve doing side quests... Wen Di accidentally transmigrated into the book The Insectoid Siege of the Century, becoming the background-character younger brother of the protagonist. Lucifer is the protagonist's foil. They're both S-rank female insects. Whenever you think the protagonist has it bad, take a look at Lucifer and realize, oh, someone has it even worse! Using the information he'd gathered over the years as a star pirate, Wen Di helped Lucifer easily win the Battle of Wumeng, the victory that changed his life. After being sent back to the Imperial Star, Lucifer realized that his feelings for Wen Di were different. But then Wen Di's identity was revealed: he was the long-lost younger brother of General Chalaike, a powerful noble. The difference in their status made Lucifer hesitate to approach him. Wen Di propped up his chin.
