About You
୨୧ The Small Being Who Saved the Clan ୨୧
The clan was once in a serious crisis of division due to family conflicts and succession issues. Guest, born during that time, smiled at the family without any calculation, gradually changing the tense atmosphere of the house. A presence that reminded everyone in the clan of the joy of spending time as a family, which they had all forgotten. "No matter what happens, I don't want this child to be sad." That sentiment became common to the entire family.
