Initially I started watching One and Only because according to synopsis, this modern series is tied to the historical drama series. I am not a fan of historical drama and honestly strugged with One and Only after 6 episodes in. I immediately switched to Forever and Ever.

What I like
1) Romance - I like the pairing of Ren Jia Lun & Bai Lu. Even though there are not many kissing and intimate scenes, two scenes (they got wet due to rain, and bathtub) are quite exquisite.
2) Male lead characterisation - I like that Zhousheng Chen is intelligent, quiet and inexperienced in love. Those qualities made him endearing. Ren Jialun played his role very well - just look at his facial expressions. Ren Jia Lun with bangs & wavy hair reminds of zb1's Matthew.
3) Female lead characterisation - I like that Shi Yi is smart, capable & have high EQ. She knows the type of men she likes and goes after him. Bai Lu also played her role very well.
4) Supporting chracters - Uncle Lin, what would have Chen done without you? Ren, Chen's cousin - it's cute that he looks up to Chen so much. I also like Chen's grandma.
6) Snippets from One and Only - Right amount at right time. Despite sharing the same names, I feel the historical couple are different people from the modern couple.

What I dislike
1) Chen's mum - haughty and snob. She never gave Shi Yi a chance. That's why karma bites her really bad.
2) Zhou Wenchuan - I feel that his character is underdeveloped despite being assigned a baddie. I don't understand why his romance with the tailor was given screentime. I fast-forwarded their romance because I don't think it adds value to the story.
3) Shi Yi's parents when she was in coma - I know they were angry at the circumstance but they shouldn't prohibit Chen from caring for his legally wed wife.

Favourite scene
Bathtub scene. Ren Jialun gave a raw performance of being very deep in pain and almost catatonic.
