Recommendations

Both series have entertaining leads and you will end up laughing during the episodes because of nonstop comedy factor

In both dramas FL pretends to be somebody else in the first meeting and not intend to fall in love with ML, their first meeting is totally coincidential

FL have a strong bond with her friend who help her out in many situations. Her family runs a small business

ML offers a contract marriage proposal to FL

In both dramas ML have a manager who is also his confidant and adviser.

Charismatic Male Lead and he thinks highly of himself

Contract become real once they start fooling others (In A business proposal for Grandfather and in Once we get married for fashion designer whom they are working with)

ML decides to propose FL

In my opinion A business proposal is more funfilled series and I love the chemistry between Shin Hari and Kang Tae-Moo (Still both share very similar background plot, go for it if you want to watch something with the same kind of story).

Kento in both movies.
Both movies are time travel
One has romance, the other one more about science.
Going back in time to fix things up

Both dramas focus on two male university students who have an enemies-to-lovers relationship of sorts at first before falling in love with each other. They both have to face various obstacles after getting together but overall lead a wholesome and heartwarming relationship. Both stories also rather prominently feature music as a plot element.

Both ML & FL both just want to have physical relationship to stay away from loneliness but soon enough they realized they like each other. Nakao Masaki is an eye candy & he is super adorable with his clumsiness in the drama. Both dramas adapted from manga/comic book.

Sakurada Dori is adorable as a high school student. In both dramas both ML & FL needed love & physical relationship to avoid loneliness both ML & FL realized that they already falling in love with each other. In Liar is more to office love affairs & in Kuzu no Honkai is more to high school love affairs. Both dramas adapted from manga/comic book.

In PC FL is having an affair with her boss in her workplace but in Soredemo Ai wo Chikaimasu ka? ML is having an affair with his high school friend a single mother. FL found out ML her husband having an affair is trying her best to win his back & she was involved wtih a bit fling with her junior co worker but is a very short temporary fling coz she realized she love her husband. Both dramas adapted from manga/comic book.

In this drama is FL having an affairs but ML as her husband doesn't have any affairs with anyone but SML is her affair partner. SFL is SML wife doesn't stand still while knowing her husband is having an affair. Both drama based from manga/comic book. Suzuki Nobuyuki too adorable. In reality ML aka Higashide Masahiro is having an affair with Karata Erika gosh what a.....

ML having an affair in HL but in PC FL having an affair. Both FL & ML is struggling to find their real happiness. Both dramas theme is cheating, betrayal & infidelity. Both dramas adapted from manga/comic book. Sakurada Dori always adorable.

FL stuck with office romance love affairs with ML. Both dramas equally I like not too heavy story & short drama only 24 mins/episode. Both dramas adapted from manga/comic book. Kizu Takumi is an eye candy somehow he resembles Sakurada Dori.

The kiddie actor version for the 2006 classic of the same name. I wish they make kiddie versions for popular dramas these days too, that'd ve quite fun haha.
Well I guess we have Chibi these days, but it's not the same thing.

Though I was excited to find out that there was a movie remake for the 2006 classic drama and with basically the same cast at that, it quickly turned out to be a dissapointment.
All the humor felt too cringey and try-hard, whereas the original was effortlessly over the top in a very enjoyable and funny way. Even aving the same cast could not save it.

In both stories there are:
- an important diary for the development of the plot
- a difficult school to reach

I really like Reba's performance!
She is so beautiful that I can't help screaming when I see her!
and my heart melt......
I've seen almost all her plays, and I really like them! HC!!!!!!

Both plays are performed by Reba!!!
I especially like her drama. She is really the best actor I have ever seen.
She is also very cute! I really want to see her with my own eyes 55555!!

This drama is not a heavy secret love affairs. In Soredemo Ai wo Chikaimasu ka? ML is having an affair with his high school friend a single mother. FL found out ML her husband having an affair is trying her best to win his back & she was involved a bit fling with her junior co worker but is a very short temporary fling coz she realized she love her husband. Both dramas adapted from manga/comic book. It's a bit complicated for both of them. Both of them is struggling to protect their marriage. If you like secret love affairs genre I recommend this drama.
