Bro I am too dumb for this I mean I never even read this I just joined the train like 25 c...

Tennessee imagines amber and people he cares about dying to comfort himself kinda, it's a defense mechanism to mourn someone while alive to prepare yourself for their or your death bc you know you wouldn't handle it if it did eventually happen so you do it over a long period and in case smth happens you're prepared (ofc that's not healthy don't do it )

Tennessee imagines people he cares about (especially amber) dead bc it's comforting, it's his defense mechanism. if he imagine them dead over time it soften the blow of their actual death like what happened with his friends rick and the other woman two chapters ago . so basically him imagining amber dead is bc he's scared of losing him . as for amber he's so obsessed with Tennessee that he wants to kill him to prevent him from possibly leaving him that was talked about before. and now amber is scared of " death " , since he lost his memories he considered himself someone different than the old amber . so to him regaining his memories is dying bc he'll be "another person"
not your fault for not understanding btw the translation is so shitty i only got it bc I'm so deep into psychology and have masters degree in English lolol

Thank you so much it makes so much more sense I only skimmed through this manhwa so like I had no idea wth theh on about this chapter cuz it felt like Amber already regained his memories at the end and also not since he kept talking about himself dying, but also how he's so obsessed with Tennessee so I was hella confused. I assumed the transition Tennessee talked about was Amber regaining his memories but ye, the translations are genuinely so confusing
