If you are obsessed with dramas where the rich CEO/ General Manager falls in love with a talented yet poor girl then both dramas are for you.

Similarities:
- Same male lead
- Similar female leads (I love that the woman in Sunshine of my life is bolder whereas the lead in Boss and me is shyer)
- Childhood family friend in love with male lead (and tries to break them up)
- Stay together once get together and fight for their relationship (Boss and me does have one break up)
-Male chases female first
-Many cute scenes and kisses
- Etc...

Veryyyy similar shows but I love both!

Both FL are fashion designers.
Both ML are Rich.

Other than those two not a whole lot of similarities, but both are enjoyable to watch. SOML is longer, but def worth the watch.

Office romance aspect are similar and the relationship is discovered by the girl who likes the ML and she tries to get her fired.

They both focus on a specific industry, albeit different ones (music and fashion design), and both are slow-burn romances. The ML and second ML's personalities are flip-flopped. The ML in SoML is like the second ML in tBSitK and vice versa.

Both female protagonists are fashion designers.. male protagonists are CEO's of companies involved in fashion..; male leads have annoying female childhood friends, which grew up with the agenda of marrying them.

The male protagonists' fashion company struggles to obtain a sertain clothing technic .. while the female protagonist is a designer and a student of the person who has the rights over this technic. Many episodes revolve around the obtaining of the rights for it.. others are about family intrigues and such inside the company and it's rivals. The main protagonist in both struggles due to the unhealthy obsession of two other women whom he somewhat takes as his sisters.

If you like domineering CEOs, Sunshine of My Life has one of the better ones. He's competent, self-assured and protective. The romance between the two main characters is similar too, the CEO is colder and more powerful, but the main female lead has her own agency as well.

While both suffer from use of stereotypes and cliches, Sunshine of My Life has excellent coverage of fabric, embroidery, and clothing industries, with lots of interesting clothing designs. This respect for the industry featured puts it above the rest.

The dramas have plot with Fashion world as main set, with fashion student, model gold digger and nice male lead.

The flow of the story is similar and the chemistry between the leads. Both start slow and feel kind of like slice of life.

Both 'Smile to Life' and 'Sunshine of My Life' have love triangles! The second male lead and the main guy who used to be best friends in each drama have a falling out, which makes things even more complicated when they both fall for the same girl.

ML and FL have beautiful chemistry
a mature but cute love story
if you want to watch something similar try it

Both have a fashion design theme
Female lead have a passion for traditional Chinese embroidery / style and techniques.

The relationships with ML and FL in both dramas once they come together they essentially stay together. SFL friends with ML in both dramas , working with them hoping to change the relationship by being the one at their side.
Also, in both dramas there is a SML that is antagonistic towards ML but they were childhood friends.
Both are business based dramas, one architect one fashion.
Overall feel is similar
