I Transmigrated Into the Flirtatious Male Lead's Sidekick and Took Care of His Widowed Sister-in-Law

[Book Transmigration] [Urban Super Martial Arts] [Romance and Combat] [Overpowered Junior Brother] [Harem]

Wang Xiao transmigrates into a novel as the hapless underling of a harem protagonist. His day-to-day job is to help the protagonist, who can't keep up with everything, take care of his sister-in-law...

Why does the protagonist get a woman for every thousand, while I, a supporting-character underling, am forced to pair up with a female dinosaur?

I, Wang Xiao, refuse to accept this!

Protagonists and side characters, big brothers and underlings, do we not all have the same rights?

Wang Xiao: Don't be afraid, sister-in-law. I'm no good guy, but I'm at least a hundred times better than my lousy big brother!

What? You say you want to break up with my big brother?

One day.

The harem protagonist, who'd been mindlessly picking up beautiful women outside, came home and suddenly found that his whole world had collapsed!
