It could have been a mature and healing drama.. Now the drama become a torture.. The ending is either open or a last minute happy one.. By the looks more chance for open ending..
To me the ending is more of an open endings not a sad ending.. They made up.. They still love each other.. Doona already said she doesn't want another man in her life ever again.. They will have a chance in the future.. When both of them are stable..
This show is more like cringe fest..she breaks up with them for the childhood friend.. then with the permission from him she is two timing with a new guy.. totally stupid plot with stupidly cringe ending..
