After Swapping Systems with the Manga's Male Lead

Shen Linxi is an utterly ordinary background character in a passionate shonen manga.

His only purpose is to be a lovesick fool, get exploited and discarded by a scumbag top who married into a rich family, then become a vengeful spirit and a boss in a side-story dungeon for the protagonist and his crew.

Until Shen Linxi awakened a romance check-in System.

The System told him that if he completed 99 essential check-in tasks with his lover, he could change his fate.

Little lovesick Shen Linxi agreed without a second thought.

Full of anticipation, he asked the System what he had to check in on the first day.

The System looked at the task list, its voice beginning to tremble.

"R-run... five kilometers?"

Lu Chentong is the aloof, cool-guy protagonist of the most popular heroic shonen manga around. No romance, just career ambitions.

He comes with a self-discipline System fit for a dragon-slaying protagonist.

One day, he opened his eyes.

"Congratulations! You've been bound to the 99 Little Things in Love check-in System! Go share your feelings with your crush!"

Never dated in his life, an insanely career-focused Lu Chentong: ?

Lu Chentong always thought he could never fall for anyone.

Until one day, he saw a delicate-looking flower shop clerk with red-rimmed eyes from crying punch a vengeful spirit into oblivion.

Lu Chentong's heart suddenly began racing.

The first time I went to the Louvre, I felt nothing special, because I had already met my very own Mona Lisa.* 🌹🌹🌹

Career-focused cool-guy transmigrator x lovesick, laid-back local.

Big wolf-dog top x floppy-eared bunny bottom.

One-on-one romance.
