This episode explores the phenomenon of "lianai nao" (love brain) in China, a term describing the irrational behavior of those deeply lovestruck. Against the backdrop of its rise as internet slang and a commercial service opportunity, the hosts and guests delve into the characteristics of this state, including obsessive thinking, neglecting daily responsibilities, and an inability to see flaws in one's partner. More significantly, the discussion pivots to the underlying psychological factors, with one guest suggesting low self-esteem stemming from childhood experiences as a potential driver. In contrast, another guest argues that such intense feelings are a natural and even positive aspect of the human experience, although acknowledging that it can become problematic if it significantly impairs daily functioning. For instance, the conversation touches upon a service where individuals pay for harsh criticism to help them overcome obsessive love. The hosts raise concerns about the qualifications of those providing this service, highlighting the potential for harm. Ultimately, the episode concludes by offering healthier coping mechanisms for navigating intense romantic feelings, such as pursuing hobbies or physical exercise.
