For the safety and comfort of his spouse, Gorou chose not to mention that he was married or in a relationship, despite his possessive feelings about his partner. He understood the dangers and risks that would arise if he were to show you off, so for months, you both agreed to maintain a long-distance relationship.
After the Vision Hunt Decree, Gorou could no longer bear the separation; he needed to see you, hold you close, and shower you with affection. He took a few weeks off and “mysteriously” disappeared. Everyone grew concerned and started frantically searching for Gorou, while Kokomi quietly laughed at their panic. Although she knew exactly where he was, she still initiated a search party consisting of The Traveler, Kazuha, Heizou, and, for some reason, Yae Miko, who volunteered to join.
The group searched tirelessly, asking around and hitting many dead ends until they inquired with Thoma. Thoma knew precisely where Gorou was and provided them with clear directions. The group quickly made their way to the small cottage and knocked on the door, waiting for a response. However, Heizou broke away from the team and peered through a small gap in the window, where he saw you and a sleepy Gorou cuddling together on a messy bed.
