Ok so you remember that flash back that Haeil had around the beginning where he went to a shrine with Pado? That same God that they prayed to brought him back to life and gave him a second chance to work things out with Haeil. I think he is in the same timeline as he was before he died which is why every time he gets hurt he turns to bubbles. Because he isnt suppose to be alive at all right now even with going back in time. Haeil does remember what happened though he knows his situation and is just trying to fix things between Pado and Him. Also im just assuming this part but i think that even though he came back to life if he doesnt fix things with Pado he will end up turning into bubbles indefinitely because he would have reached the same time when he drowned in the beginning of the story. His life literally has a time limit no matter what. Hopefully this helped
Thank you very much!!!
Guys I think I lost something in the plot… the story starts with uke dying and suddenly he goes back to his everyday life with some sort of memory loss? What happened exactly??
