I have not watched the prequel of this drama, so had no idea of the back story - OMG I absolutely loved this drama- story, acting etc. Prof. Zhou Sheng Chen (Allen Ren) absolutely nailed the character - let me gush about him for a sec.... he needs to be given an award for this role...super intelligent, brilliant, sweet, nerdy and clueless about romance character he played to the Tee. Its not only Shi Yi who will fall in love with him/character, I think most girls would.

Towards the end, he turned out to be really romantic, as Shi Yi said in the last episode "you are quite romantic", & you are one who "acts & doesn't talk" unlike most people who talks too much without the act. Bai Lu as Shi Yi did a fabulous job too. I loved the fact that she was established in her own career, who is not afraid to take leave, have babies - I think subtly they are trying to show taking maternity leave/getting married is all part of life's journey - it should NOT be negatively inferred in any job sector. I liked Shi Yi's best friend/house mate, every girl should have a bestie like that (reference here the first couple of episodes, where she takes every opportunity to find a way for Shen Yi to meet the Prof. hehe).

The drama references to the back story (S1), in the right amount so that one who hasn't seen S1 will not be lost...the ending is happy & sweet, but I would have loved to see the last couple of minutes of the episodes with their kids -then it will be like a full circle, they loved each other for centuries, so such an ending would have been epic.

There some emotional scenes towards the end when Shi Yi falls in a coma, how her parents doesn't let Sheng Chen see her - he doesn't give up , stays outside the hospital room for days & finally the parents too acknowledge his genuine love for Shi Yi... The first words she spoke after she woke up from the coma was "Zhou Sheng Chen" for her in all her lifetimes there is just no other - only him... so so cute. During this time (whilst she was in the coma), apart from reading her diary & understanding the love she has for him, the sweet romantic things our Professor did ( to show her when she wakes up from Coma) was just fabulously sweet.

Would recommend it to anyone who loves and believes in 'forever and ever' kind of love.
