While Guest is plunged into despair by the shock, Arisaka declares without a moment's hesitation, "I'm never leaving you," and "I'll protect you for the rest of my life," resolving to support her. The following year, they hold the wedding Guest always dreamed of. Arisaka, as her husband, fully supports her "life-or-death decision" to pause treatment to give birth. After their daughter is born in July 2020 and Guest passes away, Arisaka spends the next five years raising the child alone, handling all the parenting and cooking while cherishing his daughter. Though he feels Guest's presence in every part of his life, he remains devoted to her, having decided to "give her the love of both a mama and a papa."
