In the second season, Xiao Qi was recognized by Ou Ye in the fourth episode.

The fourth episode: Ou Ye has a new place to live, but she is used to Yu Bao's care and feels empty. And Yu Bao seems to be accustomed to the company of Ou Ye, but somehow he feels unaccustomed. Boss Li called two people he arranged and asked them to look for Rowen along the direction of Blissful Bay opposite the hotel. They went out with their pet mountain gods, but Destiny Sun reminded them that there was a typhoon landing. The two of them had to go back to the room with the mountain god. Rocky came to the couple's room with his dog interpreter. The hostess thought that the dog translator would help the mountain gods communicate with them about the whereabouts of cultural relics, so she bought one excitedly. David and Niu Tuanchang are discussing holding a lovely pet competition to expand the reputation of the pet park. Xiaoqi helps Oye pick up rubbish on the beach. A couple arranged by boss Li to explore took the mountain god for a walk by the sea. Xiaoqi started barking when he saw them, and David was there. As a hotel manager, he must apologize to the frightened couple. Yu Bao witnessed what happened. He thought the couple were abnormal, otherwise Xiao Qi wouldn't keep screaming when he saw them. Ou Ye recalled Xiao Qi's fierce reaction every time he saw them, and saw the packed broken porcelain when he cleaned their room. He thought the couple were really strange. But David thinks that Yu Bao and Oyer are too sensitive. Ou Ye told Yu Bao about a series of strange performances of Xiao Qi recently. Yu Bao thought Xiao Qi wanted to express something and wrote to Ou Ye. Xiaoqi suddenly came running. Ou Ye and Yu Bao followed Xiao Qi to a coconut grove. Ou Ye saw the box next to Xiaoqi and recalled her past with Xiaoqi. At this time, she finally understood that Xiaoqi had been guarding herself, because Xiaoqi recognized her when they met. In the evening, at Yu Bao's home, Yu Bao was holding his prosperous wealth, and Xiaoqi was lying on Ou Ye's lap. Yu Bao told Ou his own story. He once had five dogs, who grew up with him. He also witnessed the departure of these five old dogs. He told Ou Ye to take good care of Xiaoqi, because for dogs, the owner is everything to them.
