Cheng Luo, a yandere beauty who appears to be well-behaved, is actually a genetically modified "perfect container". He approaches the psychiatrist Gong in a harmless disguise and eventually locks him into a carefully crafted cage.
The gentle and ascetic doctor Gong Zhou Yun thought he was saving a fragile young man, but he didn't know that he was the prey.

Middle-level concept: A warning about technological ethics. Is the genetically modified container filled with artificial souls or human hearts? Deeper Concept: The Cage Dialectics of Love. A solid cage is a concentric prison that uses the other person's pupils as keyholes.
