Mr. Perfect and Miss Almost (2020)

They both:
~Xiang Han Zhi acted in both of them
~are rom-coms
~Stories are fluffy and cute
~Few scenes are quite cliche

The leads end up living together because they rented the same house but one person has more power than the other and could kick them out. There is a big age difference but not too big. Both pretend to be together(In My Boss is for only two episodes). Law is involved in both. And it is the usual "cold" ML with Happy FL who is struggling.

Both dramas involve a contract marriage between a couple in order for the ML to make his ill relative happy,

Both are dramas about a contract marriage that becomes true love between a poor FL and a rich ML. Both MLs marry in order to appease their grandparent.

The thing which are similar:
Age gap
Student teacher relationship
Marriage because of elders
Living together ofcourse bcos of their marriage
(But falling in love anyway:D)

Both dramas involve a contract marriage between a couple in order for the ML to make his ill grandfather happy,

Married couple, cohabitation, marriage for convenience .............................................................................................................................................................................................

Both have cohabitation between the leads that becomes a romance. The MLs are distant and highly intelligent, approaching everything mathematically/scientifically, FLs are naïve and sweet.

This drama also has contract relationship with cold male lead and warm female lead plot. They start off as just contract couples but end up falling in love.

nnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnn

Marriage without love and for convenience, I love both dramas chemistry, both ML are nice and caring.

P&C feels like a remake of full house but without the love square. So many similarities. The fraud, cohabitation, contract marriage and other nuances twisted but present nonetheless.

Two people with completely opposite personalities fall in love. Cute romance between two people. This chinesz drama is perfect if you love rom com.
Similarities :
Cold male lead but his behaviours towards the make lead are cute !
Sweet romance
Male lead is really smart
The protagonists have to share a house

I recommend this both drama because , Male lead and Female lead
try to solve problem
In one drama explosion and another student murder/suicide

Both have contract relationship. They marry without love but find love while living together. Both have cold male leads. I loved them both and if you loved either one of them most probably you'll for the other. Both have happy endings and you'll never get bored of them??
