I GOT THE ENDING!!!(im about to cry.) : REWIND TO 48:29. SHE SAYS:“even if all your memories dissapear,if a miracle where they all come back the moment you see me suddenly happened,that would be great.”
HE SAYS: “if i have a crush on you again,you hold onto me first.if i show up in front of you again,even if i whine and throw fits,endure it and dont let me go.”
SHE SAYS: “okay.”
HE SAYS:"to the me who wont be able to remember,tell me your feelings just as they are now.if you do that,we’ll be able to return to this time.
SHE SAYS: “okay.take a look.” -and points to his watch- SHE SAYS: “when i tell you how i feel,at that moment,you will return to this moment right here.” “i put you in a trance.” (skip to when i say “anywayssss sooo” to get to the point.though u should read everything to understand it better.)
1year later… what happens? THAT VERY SAME THING.A MIRACLE.THE MIRACLE SHE AND HIM WHERE HOPING FOR. WHAT WAS THIS DRAMA ALL ABOUT GUYS? ABOUT THE MIRACLES.THE FREQUENT SHOW OF THE BOOK ABOUT A MIRACLE AND THE CARD KKJ HAD IN HIS WALLET ABOUT MIRACLES. WRITTEN BY THEIR FATHER ABOUT THE MANY MIRACLES HIS SONS WOULD ENCOUNTER.A MIRACLE THAT WOULD MAKE HIM HAPPY.(i remember somewhere kkj saying that the book his dad drew for him and yoonjae was to make him happy in his life or something.a miracle that would make both of them happy.he was talking to mari or something when she was telling him that she would stay with him and be happy with him and he told her something like the miracle wouldnt be for only u to be happy or something.and maybe the miracle was orginally that one child will save the other and then vice versa when needed,but when the kids ripped the miracle,they said:what if it doesnt go back to how it was supposed to go origanally?"(double meaning for us:what if the purpose of the miracle gets changed?) no longer kkj saves yoonjae(with his sickness) and then yoonjae saves kkj(water drown thing) and now again kkj must sacrifice and save yoonjae but probably about happiness. switch-back-into-bodies-and-both-have-a-happy-life-for-both happiness MIRACLE. yoonjae will wake up with no memory,therefore,leaving him free of pain of still being in love with Gil daran or loosing her, and kkj will be happily in love with gil da ran and remembering everything.
anywaysssss so: look at the ending again. starting from 1year later. then she says “i love you” and what happens? THAT VERY MIRACLE THEY WISHED FOR.
it looks like they went back mentally(he regained his memory through that miracle),and they physically went back to the time they said they would return to(through the miracle). then kkj HE SAYS"at this moment,my heart,just like it is now,it will grow all at once.LIKE A MIRACLE"(maybe this is something he had said and it wasnt shown until now because it wasnt in the flashback but maybe he said that and she rememers it.then she is in front of him and she smiles(he doesnt say this in the flashback and they both dont smile in the flashback remember? they were crying,so this prooves they went back in time.and the miracle happened XD) THEY BOTH SMILE AND LIVE HAPPILY EVER AFTER!!!
the writers really shoulda explained this more because many ppl broke their heads over this ending,were upset,there was no closure for some things as ppl would have liked,and it was very VERY confusing.but the miracle happened and everyone is happy and perfect so good ending and bad at the same time. xD good.
