Today was my wedding anniversary with my wife, Minami. We had planned to attend our class reunion together, but I prioritized a business dinner with clients and ended up missing the chance to talk to her. When I returned home late from the reunion, I finished preparing for our anniversary and messaged Minami, but received no reply. I contacted other attendees and learned she had left somewhere before the after-party. Filled with anxiety, I had no choice but to search for her and find out where she was.
