Yes, this seires did have a sad ending and I do think that Yu Xi Gu deserved better but not all love stories have a happy ending and that's why I think it's underrated. Most people want a happy ending where they end up getting married and living happily ever after but like I said not all love stories have that kind of ending, which makes it more close to reality. The acting was great, I really felt the emotions of the characters and I would watch this again even after knowing what happenes. I did feel bad for Yu Xi Gu's boyfriend (forgot his name lol), he was stuck in place and never moved on. The actors stole my heart and I'm greatful that I got a chance to see this story grow.
