I think we are seeing him come home from working in a play slowly building his career back.. So some time has past. He is one better terms with his step sister and has a more healthy attitude. He has been living in their little rooftop waiting for her, and when he arrives, there are footprints in the snow leading to their apt. That is made significant so I think she has come home and he is just finding out. She is inside cooking, so she has made herself at home. He is tentative and asked about coming in and she says 'of course', because of course they are together.
The grandfather is ok and back home.. perhaps the guy and his mother are there helping with the place now?
Jae Min had left for the US for 3 months to shoot on the movie, but we don't know how much time has past but we do know that him and Seol Woo and Young Woo are all still friends and he is invited to their house. The ending is acceptable to me.. I like a kissing ending because I am a dumb romantic sucker for that, but this did let us know all we needed to know I think. Just my opinions..:)
NooooooooOOOOOOOOOOO I DID NOT READ THIS TO FIND SUCH A RUSHED AND UNSATISFACTORY ENDING. I dont know if its just the art or how the author drew out the ending scene, but it felt like they didnt make up in the end or smth. Like why would Seol Woo ask if he could come in if theyve already made up? Or Jae Min wondering if Young Woo was going to return? What exactly happened with Young Woo and her family stuff? Also, alot of their problems would have been avoided if Mr Yang had just grew a pair and claimed Ha Yoon after Young Woo came into the picture. =_= but even after all this, it was still a rlly good read, not gonna lie.
