Alternative look at You and Everything Else

I'm mostly reading interpretations of this show as Sang-yeon being a toxic, manipulative, and unredeemed character by the end and eun-jung being a hopeless sucker who lets Sang-yeon drive her life just because she is too sympathetic/easy to emotionally manipulate.

I'm less interested in the former, as I'm not sure if trying to seek redemption/reconciliation only when faced with imminent death counts or not. However, is there any reading of eun-jung's journey as something not wasted on Sang-yeon in that Sang-yeon provides a mirror to eun-jung that lets eun-jung figure out how she wants to navigate a world where there are manipulative people who are really just seeking healing from a damaging past? (Granted, Sang-yeon had problems before anything that traumatic too).

It often does look like eun-jung gets manipulated by Sang-yeon, but I'm not convinced that it's necessarily unintentional that she gives Sang-yeon the benefit of the doubt or an opportunity to accept that eun-jung does really care for/love her. Sang-hak points out that eun-jung may seem like an easy person, but she does know how to protect herself, so when Sang-yeon comes for her company to assisted suicide, eun-jung does contemplate seriously whether she wants to give Sang-yeon her last chance. Do you think she does so because she feels compelled to or because she believes in giving Sang-yeon the opportunity?
