Teacher-researcher identity is commonly conceptualized as one of the central components of teachers’ professional identity. Such identity development is not only configured toward the past and present but also oriented toward the future. This retrospective duo-narrative inquiry aimed to portray such orientation by exploring the possible selves envisioned by two female Gen-Z EFL teachers upon the completion of their Master’s graduation theses in the Mekong Delta region. Informed by Possible Selves Theory, this study drew upon qualitative data collected from semi-structured interviews with two primary participants and two outsiders for data triangulation. Subsequently, data were analyzed utilizing thematic analysis for each case, followed by a cross-case analysis to identify convergences and divergences in their lived experiences. Findings revealed that participants reconstructed their teacher-researcher identity through three dimensions of possible selves, including the hoped-for, the ought-to-be, and the feared. They envisioned their identity as personally developed, institutionally grounded, yet potentially at risk of being contextually dissolved. The study was pedagogically significant for maintaining teachers’ motivation in the teaching profession through an envisioned sense of possible selves. Pedagogical implications were offered to inform Master’s students, teacher education programs, and tertiary institutions in Vietnamese contexts and beyond.
