This study attempts to raise a question about general death and awareness on time with regard to discussing the poems by Lee Sang. Accordingly, it revealed that death is rather a time of life and a methodology of writing considering the awareness on death in his texts as 'another death,' which means 'dying,' and looking at it differently from the perspective on general death (difference between death and dying). Furthermore, focusing on hetero chronie, which is the heterogeneity of time to extend the time of life, it examined the path of transcendental self-overcoming that reaches eternity. Death in the poems by Lee Sang is the substance of death which is not in the past or future but now in progress. Experience of 'dying' is the experience while living, which allows us to understand the paradox that death is life, and he reaches the true introspection beyond narcissistic self-reflexity. 'Dying' is a journey that cannot help going out of existence and a process that leads to the impossibility that cannot be escaped from this cycle. He called for literary imagination as a way to transcend the impossibility, expressing the immanence of biological death. The approach to 'dying' in the text is the hardship for the subject to face the impossibility of existence in the world. Lee Sang in a state of being undead broke up the dichotomy of life and death. Therefore, this study investigated that death―the moment when one is in the act of nihility―represented eternity reaching infinity and that representation was produced into writing. Based on Blanchot’s thought that the view on 'impossibility of possibility' of death goes beyond the completion of existence and rather dismantles existence, it figured out that imagination of death in the texts by Lee Sang meant the will to live. On the basis of this, the paper presented another way of reading the temporality of time in Lee Sang’s poems.
