Story: The synopsis posted above is a good summary.
The story started not long after LianXin had gotten her transplanted corneas; she had been a close friend of the older Yu Qiu, Luo Ting, and Chen Ji. Before her death, Luo Ting had asked YuQiu to give her eyes to little LianXin. LianXin then was adopted by Luo Ting's family, who opposed her relationship with YuQiu.

Overall I quite liked the childhood portion of the drama - the child actress was great and the relationship between our main characters was building nicely. The drama showed how their bonds shifted throughout the years - when LianXin became a teenager, then a young lady. Finally, the second half of the drama settled on LianXin's "adult" life - she reconnected with Yu Qiu and her closest people after returning from her study abroad. Her Alzheimer's onset started appearing subtly toward the end.
Personally, I found myself skipping half of the scenes as it was repetitive - they recycled some of the plot arcs over and over again.

This is my first time watching the main male actor (Eric Yang); his acting was decent. The other actors did well, too. (except maybe Run Chen but oh well) - I LOVE the child actress playing little LianXin!

I wouldn't rewatch nor recommend the series, tho.
Felt too long and bland for my personal taste.
