Do Do Sol Sol La La Sol (2020)

-Spoilt, adorable & naive FL
-Swoony, kind ML
-ML teaches FL the ways of the world
-Adorable, fluffy chemistry

The otherwise rich lead is reliant on the other lead for money in both the dramas in the initial episodes (this scenario is more prevalent in DDSSLLS). More over, both have a similar feel-good factor and a lot of heart!

Both dramas are about adult life. The male leads in both dramas are calm, hardworking, and only work part-time. That's how both of the female leads meet the male leads. Instead of the male lead's family going bankrupt, in this drama it's the female lead's family. Because of a problem, the female leads in both dramas almost have their dreams taken away. The female leads in both dramas are adorable and hilarious.

The shows are similar in the following themes:
> The Female Lead must navigate a world that feels different from her own and, therefore, she ends up relying on the Male Lead's help and guidance.
> Both leads grow up in a rich family.
> The Male Lead isn't as honest with his feelings towards the Female Lead at first. Though in both cases, their actions are more honest than their words.
> The Male Lead chases the Female Lead first.
> One of the leads is a successful piano player. In CL, it's the ML while in DDSSLLS it's the Female Lead.
> The Female Lead is a bit spoiled but in a fun way.
> The Female Lead is betrayed by someone close to her.
> The Leads met each other prior to the start of the show, with the ML remembering that encounter before the FL does.
> The ML lost someone really important before the start of the drama, which still causes him pain.
> The FL lost her birthmother when they were young.
