If you don't mind the language difference, then try this drama too: Marry Me, Or Not.
The similarities are as follows:
1. Male lead not wanting to marry and wants to live alone
2. Male lead using female lead to achieve his want of staying single
3. From fake relationship, the couple learned to love and value each other and turned false relationship to true love
4. Old couple in verge of divorcing, who communicates through sticky notes/boards/cellphones
5. Male Lead's Mother against Female Lead and prefers to have an obedient daughter-in-law
.. also, the couples in both dramas have great chemistry. They'll make you feel giddy inside. For Rom-Com Fans, this is a much watch.. very light, romantic and funny story.

1. Both dramas deal with crime and investigation
2. In both exist corrupt officials who are willing to do anything for money, position/power
3. Villains in both dramas develop twisted personalities bec of how they were raised by their father
Personally, I enjoyed both of these dramas, they both kept me interested and both have amazing casts in which you'll love the protagonist and really hate the villains to their bones!

Both dramas is about reconciliation bet divorced couple. . .how fate allows them to meet again, forgive each other and start all over. Both drama couples have great chemistry, and both female leads are very pretty they matched the male lead very well.

I know they have different genre, bit there are still some similarities. Both main leads are innocent and had to sacrifice for their love; one is love for his lover while the other is love for his sibling. On both dramas, the male lead fell in love with the stepdaughter of their first love.
