Let me tell you something... If I had to choose only one BL series to watch again and again for the rest of my life this would be it. This is my favourite bl of all times. It's just a classic.
Great storyline, amazing acting and chemistry between both couples. You can feel the love, the insecurities, the challenges of each and every character. I know that at times it can be sad or sentimental but to me it is the most honest portrayal of true love.
I have watched it three times already and I'm about to watch it again. Do yourself a favour and don't miss this one.
