有田一臣
A florist and Takeda's former classmate. Quiet and soft-spoken on the outside, Arita's heart carries anger and sorrow that are rarely given voice. Throughout his cohabitation with Takeda, both the joy and pain of living together gradually begin to unravel these emotions, as Takeda's kindness becomes both source and solace from Arita's struggles.
