Oh, it most certainly would. A sequel to this manhwa could offer deeper insights into the world it created and potentially reveal hidden aspects of the story. It would be a treat for fans who can't get enough of it.
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 think 'a knowing sister manhwa hentai' could imply a manga that involves a sister character in a somewhat risque or adult-themed situation. But without more information, it's hard to say for sure.
One great story to share is 'The Velveteen Rabbit'. It's a heartwarming tale about love and becoming real. Another is 'Charlotte's Web', which shows the power of friendship between a pig and a spider. These stories can create a special bond when shared with a sister.
