The one in the coma is Tani's little brother. I think Tani agreed something to a God which is the reason why he is cursed into a dog. His real body only comes back when the uke kisses him for a short span of time. And the curse will only be destroyed if the two will truly love one another. It's like beauty and the beast story lmao haha
oooohhhh, thank you, now i know. heheheh
Oh!!!!! This makes sense when the parents were saying that a Tae Young is still shocked and that he's not coming home. So Tani is actually Tae Young and the reason why he is so good with Coco was because he had a little brother! Now why does it seem like Tani doesnt remember anything?
i think tani's real "body" was the one in coma? annd his soul is just on the dog ir something? idk, im just making up things hehe
