On the twenty-eighth day of the twelfth lunar month, in the Happy Sunshine Garden homeowners' chat group, Luo Sufeng sent red packets consecutively, and Yu Ting also grabbed over seven hundred yuan. Soon after, Wang Junming claimed to be the son of Luo Sufeng and requested a refund, but met with a cold reception. Accidents happened successively in the building, Zhu Yaya and Wang Youlin were successively sent to the hospital, and rumors made the entire building uneasy. Yu Ting found clues from the chat history and cooperated with Officer Lin in the investigation. An anonymous piece of drawing paper uncovered the secret of the abandoned garbage chute, and Wang Junming was finally arrested. Behind the truth, Xiao Yang and past events from ten years ago surfaced. She admitted her faults before her father's tomb, determined to reform earnestly. Yu Ting returned to her mother's side, cherishing ordinary life even more.
