I love this! The topic about a grown man with child falling in love with a young man is just adorable.
But what I love most is, that Shi Yi is to straight forward with his feelings. He just accepts that the one he loves is a man - simple as that. He is so damn brave!
And with his braveness he "pulls Fei with into the sunlight" (I adore this quote so much). For me, the series is just one big celebration that love is love. Of course Yo Yo being a child just accepts the fact aswell - I have the strong believe that if children are tought open-minded this is exactly the reaction they would have. Education is everything!
The music is awesome aswell.
So, this is one big watch-recommendation and for me one of the best shows about "mature" love-stories.
