I’m looking for a (I believe) shojo manwha. The story starts with the MC (teenager girl) is moving out from the house she use to live with her guardian (the male lead, I’m not sure whether he’s her uncle or not). The MC said something about ‘goodbye my childhood’ or something else then it flashbacks to when the MC and her guardian first met. Her guardian is a young rich handsome man and has to raise the orphaned MC alone. I remember something about the MC being close with the boy same age as her and the boy’s mother helped the MC when she had her first period.
I think we will have to wait for much longer because Nono, who is a storyboard artist of this manhwa, is currently working on Don’t mess with the puppy (Paws & Claws). That webtoon just changed both webtoon author and adaptation writer.
