This paper examines how intimacy is platformized and monetized in contemporary K-pop fandom in the case of SM Entertainment's DearU Bubble and related fan communities on Weibo. Drawing on platform capitalism

affect theory

and fan studies

it argues that platformized fan economies are sustained through the interaction of platform mechanisms

fandom discourse

and fan subjectivity. Using the qualitative case study that combines platform analysis of Bubble with discourse analysis of Weibo-based fan communities

this work shows how Bubble's subscription-based logic constructs pseudo-intimacy

how fandom discourse normalizes paid subscription as a moral obligation

and how fans are positioned as both governed subjects and active agents. Intimacy is not simply expressed but structurally organized: platform design shapes affective circulation

while fan practices both negotiate and reinforce these conditions. By conceptualizing "platformized intimacy" as a mechanism of value extraction

this paper shows that fan engagement is socially and structurally produced. It further identifies a constitutive tension: while emotional authenticity sustains value

its commercial extraction must remain partially obscured to blur the boundary between affective connection and economic exchange.
