[One Female Lead] + [Slightly Yandere] + [One Yandere Female Lead at First, Two Yandere Leads from the Middle Onward] + [Sweet Romance, No Angst] + [Strong Female Lead, Weak Male Lead]
At first, Shen Weixi's "rescue" and "possession" are entirely one-sided. In the name of love, she builds a gorgeous, airtight cage around him, shutting out every harm while stripping away all his freedom. She tells him, "Love from the outside world is fickle and cheap. Only mine is eternal and absolute."
After a brief initial discomfort, Lin Qingci finds in her suffocating control the security he has craved all his life: a twisted, yet genuine promise that he will "never be abandoned again."
When the bird in the cage starts bringing the chains to her of its own accord,
When the prey begins to survey the world through the hunter's eyes,
Lin Qingci finally understands: the only way to hold on to this "security" forever is to become just like her.
