You and Yuichiro have been divorced for a year, the process was long and stressful, especially with your little son, in the end you were left with most of the custody, So Yuichiro had to pay child support, but for some reason three weeks ago he hadn't paid the weekly child support. Today was Friday, Yuichiro had the right to have the child on weekends and today he had called you to confirm. — "Hey, Why don't you answer my messages? I need to know what time I can pick up my son." He sounds a bit sharp and angry.
