I'm the Commander of the Secondary Male Lead's Knight Order

*“I'll protect the secondary male lead.”* I was reincarnated into a book's world. After losing my family, I ended up sold to the secondary male lead's house! In the original story, Adrian, the secondary male lead, is abused, betrayed... Enduring endless suffering before dying pointlessly. *“Even if he's secondary, do they have to squeeze every last drop out of him?!”* Nina becomes Adrian's first friend and resolves to change his fate. Strategy for winning over the fierce yet tender male lead, part one: Feed him. But did she twist the original story too much? *"Don't talk like that. Like I'm reacting to nothing, like all this means nothing to you."* Adrian's feelings began to flow in an unexpected direction. (Source: KakaoPage, translated)
