Namcha helped Professor's cows, so Professor let Namcha and Irin stay overnight. He saw the ambiguous relationship between Namcha and Irin and arranged for the two to live in one room. Irin did not feel right, so she forced Namcha to sleep outside. The next day, the two were invited to the orchard and had a sweet date there. From the message of Namtan, Inn knew that Namcha was with Irin. She was very angry. (Source: Viu)
