Whether people can offer one another a mutual and complete emotional response in intimate relationships is a basic question for understanding the structural limits of interpersonal emotional interaction. This article argues that such responses are rarely achieved in practice. Moreover, this gap reflects a structural limitation rather than a moral failure. Through a survey of 50 adults and 10 semi-structured interviews, this study develops, on that basis, the core concept of the "0.5 Dilemma". Participants supplied approximately half of the scale's maximal emotional responses in attentiveness, self-disclosure, commitment stability, psychological transparency, emotional resonance, emotional maintenance, and reciprocal giving. The average normalised sufficiency score was .48, with a standard deviation (SD) of .06, significantly below the .50 midpoint, t(49) = −2.15, p = .037. The emotional gap was largest on the attention dimension, while commitment stability showed the highest normalised sufficiency. Participants aged 40 and over reported less sufficiency than younger individuals. The interviews revealed distraction caused by competing mental load, silence to protect the other, and waning empathy. The paper then argues that the claim that emotionally expressive androids are "deceptive" is based on an unrealistically full picture of human interaction and proposes three ethical limits for silicon-based completion: transparency, social facilitation, and autonomy.
