Si Yun had the constitution of a side character. Through one mishap after another, he always ended up as a tool for someone else's face-slapping.
A Side Character System told Si Yun that the fortunes of several worlds were waning, and their chosen heroes couldn't save them. They needed a talent like him to lend a hand.
On one mission, he worked undercover alongside the male lead, then wavered in his loyalty and defected to the enemy, only to be executed by his own side in the name of justice.
In a Western fantasy world, he was a prince who helped a princess and a mermaid find their happily-ever-after, and a dragon hunted down by a knight.
In the Abyssal Demon Realm...
At last, Si Yun got a vacation! He became the young master of a top family in an interstellar world, a super-rich, handsome heir who could do whatever he pleased.
Even on vacation, he couldn't escape the influence of his side-character constitution. He ran into a son-in-law hiding his true talents, a good-for-nothing young man bent on overthrowing the nobles, and more...
Si Yun didn't want any trouble. He just wanted to spend his vacation cultivating his mind and soul, in peace, tranquility, and elegance.
But the worlds he'd worked in were different planes of the same universe as the interstellar world?! And all his old acquaintances had shown up?!
Huh? You realized you'd misunderstood me and now deeply regret it?
Huh? The princess was actually in love with me?
My peaceful, tranquil, elegant vacation!
