Three young people with different identities and backgrounds moved into a century-old old mansion in New York City, and met the current owner of the mansion, Feiniao, and her three friends. In Feiniao's words, "Don't touch anything that is locked." The curious rich kid actually kept breaking the rules to try to uncover the secrets of the mansion. Among them, seven young people living in New York City encountered different stories of their own lives, love or career, friendship or adventure. As the secrets of the mansion are revealed, the cause of death of the previous owner of the mansion gradually comes to light, and Asuka will have a thorough head-on confrontation with those with unknown origins and malicious intentions who are after the so-called "treasures" in the mansion. Sometimes dullness is also a part of life. I hope that when I wake up, the mansion will be as peaceful as ever.
