Please I just need the ending properly explained ╥﹏╥

after jooha woke up from the hospital he lost his memory and didn’t know who dooshik was anymore but dooshik still stuck by him and started a new life with him even if he didn’t remember him and in the end when he fell into the water he finally remembered him again, im not sure if they die though, i don’t think they do im sure they both survive after he remembers

Yeah that's the thing. Did they die or not? I'd like to think not but it would be good if the epilogue stories can expand on that
