Chanjuan, who claims to be an ancient princess, runs a "Museum of Exes" in the city while looking for unfinished love. Only when you can't let go of your ex will you see the Ex Museum. The Ex Museum collects all the love relics of your ex in the world. As long as you exchange the items and stories with the owner of the museum, Chanjuan, she can help you get out of the shadow of broken love. After reopening, they were able to welcome one guest every day. Phoenix crowns, death certificates, rouge, wedding dresses, embroidered shoes, long hair, B-ultrasound sheets and other items and stories were successively collected in the museum of their predecessors. Chanjuan also helped them reconcile with their exes one by one. It's just that every seemingly unrelated item and guest seems to have some story that connects them all. The owner of the museum, Chanjuan, seems to have some magical ability to predict their stories, and the items they left behind are returned to Chanjuan as if they were returned to their original owners, and it seems that Chanjuan is collecting these items intentionally. At the end, Chanjuan slowly revealed the mystery. It turned out that the real purpose of the Ex Museum was that she was waiting for his ex. His ex had actually been in this story earlier, but he had forgotten her. Chanjuan exchanged all her ex's belongings for his memory, but after the two got together, they had another kind of farewell...
