Episode 19 recap: Lou Yuan's mother found out that Lou Yuan and Dong Dong En are together.

Lou Yuan noticed a nice pair of rings and wanted to buy them together with Dong Dong En. Dong Dong En's parents returned from their trip, and Dong Dong En came to pick them up. When Dong Dong En's mother saw Dong Dong En wearing a necklace and noticed the rings, Dong Dong En told her that Lou Yuan had proposed to her. Lou Yuan's mother saw the necklace on Dong Dong En's neck and asked if there was something going on between Lou Yuan and Dong Dong En, urging him to confess.

Li Li An took the initiative to talk to Lou Yuan, and just as Lou Yuan saw Dong Dong En and his mother passing by, he quickly caught up with them and asked Li Li An to go shopping with his mother while he talked to Dong Dong En about the restaurant matter. Lou Yuan's mother said she would be fine on her own and asked Li Li An to go find Lou Yuan. Lou Yuan felt like his mother wanted to match him with Li Li An, always urging him to talk to her.

Dong Dong En thought it was possible, and Lou Yuan thought that Li Li An might also have some feelings for him. Lou Yuan asked Dong Dong En if she would feel jealous, but Dong Dong En said she wouldn't. Dong Dong En expressed her trust in Lou Yuan, believing that he wouldn't develop feelings for someone else, so she was confident in him. Moreover, having someone who liked her boyfriend meant that her boyfriend was excellent.

Lou Yuan felt that it wouldn't do, he still needed to make sure Dong Dong En was firmly his. Lou Yuan noticed a nice pair of rings and wanted to buy them together with Dong Dong En. The shop owner said they were handmade rings, and there was only one pair in the world, which would be perfect for the two of them to wear. Lou Yuan took the rings, got down on one knee, and gave them to Dong Dong En. Dong Dong En felt like it was a proposal and felt a bit awkward. Lou Yuan expressed his seriousness, and Dong Dong En should give him a formal commitment. Dong Dong En accepted the rings.

Dong Dong En received a phone call, saying that the designer wants to terminate the contract. Lou Yuan's mother thinks that if the designer wants to leave, it means they don't have fate. Dong Dong En feels that it's her fault for not arranging things properly, but Lou Yuan's mother doesn't think it's related to her. Dong Dong En mentions that they have an alternative designer who is currently in a semi-retired state, so they didn't bring him up. When Lou Yuan's mother sees the person, she immediately expresses her disapproval.

Dong Dong En also finds it strange and doesn't understand why Mr. Chen is not suitable. Lou Yuan tells Dong Dong En that Mr. Chen was their neighbor when they were young. At that time, Lou Yuan's mother used to sell soybean sauce and their life was quite difficult. Mr. Chen often helped them, and he had a good relationship with Lou Yuan's mother. However, Mr. Chen later went to another city, and they lost contact. Dong Dong En doesn't think there is any grudge between them, and if Mr. Chen were to come back, they might still have a chance.

Dong Dong En and Lou Yuan go to find Mr. Chen. Dong Dong En shows Mr. Chen the ideas they developed, and Mr. Chen says he will consider it. Dong Dong En accidentally breaks a picture frame in Mr. Chen's studio, and he suggests they go to the yard to fix it since there is wood available. That evening, they chat in the yard. Dong Dong En feels that sometimes there are things that can't be said due to various circumstances, but Lou Yuan says that unlike herself, she expresses her feelings directly. The next day, Mr. Chen agrees to design for them, but they are unsure if Lou Yuan's mother will approve.

Dong Dong En's parents return from their trip, and Dong Dong En goes to pick them up. Dong Dong En's mother notices the necklace Dong Dong En is wearing and realizes it's an engagement ring. Dong Dong En explains that Lou Yuan proposed to her. Dong Dong En's father is not happy and thinks that since it's a marriage proposal, it should be more solemn, not something bought from a street vendor. Dong Dong En says that she is not after Lou Yuan's money, but her father sees it as a matter of attitude.

Lou Yuan's mother sees the necklace on Dong Dong En's neck and asks if there is something going on, urging Lou Yuan to confess. Lou Yuan admits that she likes Dong Dong En and has already proposed to her. Lou Yuan's mother thinks that Lou Yuan is not reliable enough and should be more serious, so she suggests they go together with Li Li An to buy a ring. Lou Yuan's mother picks a large diamond ring and brings it to Dong Dong En's home to give it to her. However, Dong Dong En feels that it is too precious to accept. Coincidentally, Dong Dong En's parents return home, and Lou Yuan's mother arranges for everyone to have a meal together.
