Since a lot of people ask, what does jasmine have to do with this drama, I thought an explanation might be in order.

The Chinese drama title 莫离 (mò lí) can be translated as “never part” or “do not leave”. It's a close homophone to 茉莉 (mò lì) which can be translated as “jasmine.”

There's a saying

送君茉莉, 愿君莫离

sòng jūn mò lì, yuàn jūn mò lí

which means

"Sending you jasmine, wishing that you never leave".

There are also homophones in the character names:

The character played by Bai Lu is 叶璃 Yè Lí while the character played by Cheng Lei is 墨修尧 Mò Xiū Yáo.

Jasmine flowers have been included in promotional materials and Bai Lu had a jasmine branch when she sang the OST with Cheng Lei during Hello Saturday:
