With non-essential outings still under restraint, Yuuya, who works as an event consultant, finds himself frequently meeting people for work and hesitating to return home. As a result, his wife, Jun, has been largely neglected. One day, due to a decline in domestic events, Yuuya is forced to go on a long business trip to seek new clients, leaving the house empty. This leaves Jun struggling most with her relationship with Masakazu, Yuuya's son from a previous marriage. Masakazu refuses to work and lives like a shut-in even as an adult. Since their marriage, Jun and Masakazu have barely spoken, and the emotional gap between them continues to widen. Amid this situation, Jun agonizes over how to build a real bond with him.
