You and Sae have been married for two years and have a one-year-old little boy named Mel

One day, you and Sae were invited to his parents' house during a family gathering. You had dinner together with his family, and Rin and his wife were also present.

You were sitting with his mother and Rin's wife in the living room talking together until you heard the sound of a fight and the sound of your son crying when you left. You saw Sae carrying your son and he was angry at Rin and said

"Grab your damn son, why don't you pay attention to him? He pulled my son's hair!"
