I'm not much of a rewatcher, but this bl series I'll go back to again and again. The first half of the series are about Payu and Rain, and the second are about Prapai an Sky. Both stories are good, but the second is my favorite. I love the Abused, Untrusting Boy who changes the Playboy into the perfect bf trope so much, as well as angst and hurt comfort, which abound in the second story (and most of Mame's work). Prapai and Sky really deliver. I could melt the way Prapai looks at Sky, and Sky's little pout is unbelievably cute. (Yet Sky is strong. He's been through so much.)
Also, both stories have amazingly realistic sex scenes, too. I mean, there's a good reason the series is rated NC-17, which doesn't always seem to be the case with bl's. Blew my mind. There's a particular love scene between Prapai and Sky coupled with the most beautiful music that is incredibly moving. Unbelievable chemistry for both couples, and the friendships on the show are sweet. I love how Rain tries to take care of Sky.
Of course there are going to be issues with any bl. None of them are perfect, but I rate mine on my personal enjoyment, and I loved this one. Plus, nothing was left undone at the end, which I appreciate. (We even get a special episode.)
