I’m the Sub Male Lead’s Knight Commander

"I’ll protect the second male lead."

I was reincarnated into the world of a novel. After losing my family, I was sold off, and of all places, I ended up in the home of the second male lead.

The second male lead Adrian is abused, betrayed, and used throughout the original story, and, ultimately, meets a hollow, miserable death.
"Even if he’s just the second lead, does the story really have to drain him dry like this?!"

Nina decides to become Adrian’s very first friend and change his fate.
How to Win Over a Suspiciously Gentle Male Lead, Step One: Feed Him Well.
But maybe she twisted the original story a little too much.
"Don’t talk like that. As if I’m overreacting to nothing, as if all of this means nothing to you."
Adrian’s feelings begin to take a turn, in a direction Nina never expected.
