Hopefully you're 'what if' come true :C
Your theory is actually very interesting and possible !
Either way the only way this story could end happily is by him being alive.
omg so interesting!ヾ(☆▽☆)
This would totally explain why her sister can't see him! I hope it's true because I love Taeil so much. ;-;
I thought about it too ~ but one of the chapters he said that he remember how he died or he knows the place smth like that, which killed all my hope... but maybe it was lack of translation.... I realy like him soooo much
What if Taeil is in a coma, but doesn’t want to go back for whatever reason. This would also explain why the sister can’t see him and why he can’t move on.
I know it might not make sense but I just want them to be together T^T
