Well, to figure out if it's your mother or sister in the manhwa raw, you need to pay attention to the details like their appearance, personality, and interactions with other characters. It might take some time to get a clear answer.
I'm not entirely sure as I haven't read it specifically. But generally, it could be about a concept where one character tries to take or utilize the talents of others. It might involve a story of power struggles, self - discovery, or moral dilemmas related to this idea of making someone else's talent one's own.
Since I haven't read the novel, I can't say for sure who the main characters are. They could be a young person who discovers their talent is being targeted, and an antagonist who wants to take that talent for their own gain.
I don't really know. It depends on whether the creators have made the raw version accessible. You could check some popular manhwa communities or scanlation groups, but be careful to follow the rules and respect copyright.
Some local bookstores that specialize in anime or manga - related items might also carry 'Your Talent is Mine' light novel. It's also possible to check out second - hand bookstores, which could have it at a more affordable price.
