In the setting of the story, Yan Yi's almost paranoid possessiveness and "repentance" behavior towards Yan Xiao are essentially an extreme expression of distorted emotions. From a psychological point of view, this may be due to deep attachment disorder and desire for control. The lack of love in childhood or family trauma may cause him to mistake "possession" for "love" and satisfy his inner lack of security through coercive means.
The outbreak of "confession" is more like the intensification of the contradiction between long-suppressed guilt and paranoid love. When he realizes that coercive behavior cannot truly own the other party, he tries to use self-destructive atonement (such as self-mutilation, public evidence of guilt) in exchange for attention, and even regards "being punished" as a way of emotional connection. This kind of behavior is still essentially a pathological psychological pattern - even when repenting, it tries to use "sacrifice" to kidnap the other person's emotions instead of truly understanding the meaning of "respect".
The recurring images of surveillance, positioning, and scars in the story are actually metaphors for emotional imprisonment under unequal relationships of power. Regardless of "force" or "confession," the core is one party's mental control over the other, and the repetition of "I'm sorry" is more like an attempt to use language to dissolve the actual harm caused by the behavior, reflecting the complex entanglement of the perpetrator and the victim in a pathological relationship.
