In this paper

we selected the users of TikTok 'Raising Little Fireman' as the research object

and used the research methods of participatory observation and interviews to analyze how these intimate relationships are presented in the form of emotional labour

and explored the phenomenon of the construction and alienation of digital intimacy under the perspective of emotional labour. By analysing users' motivation for participation

the path of emotional labour

and the alienation of emotional labour

the study finds that the "Jointly Raising a Little Fireman" promotes the establishment of non-physical

high-frequency interactive digital intimacy

but it also leads to problems such as the alienation of time

the alienation of interactions

and the alienation of memories. This paper reveals how digital platforms discipline users through emotional labour

suggests ways for users to resist emotional labour

and emphasizes the need to pay attention to the impact of social media platforms on digital intimacy in the digital era

in order to promote the construction of online intimacy.
