This study qualitatively investigates early adolescents’ (ages 11–13) use of open-chat platforms, focusing on how they form relationships with strangers, engage in emotional practices, and perceive and respond to risks. Data were collected through a focus group interview with six participants, non-participant observation of public chatrooms, and analysis of relevant social discourse. The findings show that early adolescents use open-chat as a space for interest-based communication, information seeking, and emotional exchange. They develop intimacy with strangers through strategic self-disclosure and empathetic responsiveness. These relationships are fluid, maintained or dissolved depending on emotional needs and situational contexts. Participants also recognize a range of risks and employ coping strategies such as adjusting their self-disclosure, exiting chatrooms, and using reporting tools. Furthermore, they respond to parental control and societal perceptions through acceptance, evasion, and negotiation, often engaging in emotional regulation. This study reframes early adolescents as autonomous agents of digital practice instead of passive recipients of protection. It contributes to a deeper understanding of online intimacy and digital citizenship, as well as provides foundational insights into educational and policy responses.
