Yuushi is staying at a hotel due to an extended business trip, returning to his room each day exhausted from work. Amid this routine, conversations with hotel staff member "Ise" begin to bring a sense of comfort, gradually drawing his heart toward her. Overworked due to staff shortages, she continues her daily shifts, and their brief chats during breaks or notes left in the room naturally bring them closer. But as the day of his return to Tokyo draws near, Yuushi, now fully aware of his feelings for her, struggles with what to do.
