Not normally a fan of far out dramas with crazy plots I was not originally that into this show as it had constant misunderstandings created by kissing. It actually grew on me as the story went along because of the great acting by the main leads and the great music (especially the last song on the closing credits and the one Tong Yan and Tong Yin sing at his senior center showcase). Why would the show confuse and horrify it's viewers in the last minute of the last show? You got me. Have no clue. It could have stopped before that last minute and been what most want: a story about genetics you can't change, accepting yourself for who you are, forgiving those that have wronged you, and finally finding true love. Instead we have a final scene that is hard to watch and comprehend. I won't condemn the overall show because it does have redeeming qualities. I just want to warn everyone that, as others have stated, the ending definitely is a 180 degree difference from the rest of the show.
