I’m Just A Supporting Role, Can You Raise Me?

Read manhwa I’m Just A Supporting Role, Can You Raise Me? / 무협지 조연인데 키워주실래요? I possessed the body of a character in <The Young Masters of the Namgung Palace>, a martial arts webtoon where people die.
I was also a supporting role who was abandoned by the family and killed first. This is not gonna happen! I’m going to save money and leave this family before the original starts!
After deciding to do that, I showed off the part-time job skills I had honed in my previous life. Even the strongest brothers in the armed forces, the unfortunate crown prince, and the incarnation of revenge, Magyoju.
He’s been associated with a nine-year-old martial artist?
According to the original story, it would be a bad ending where everyone dies……. All right, I’ll save everyone from this.
A well-raised supporting role saves several main characters!
