It has similarity because the guy like his own sister even though they're not blood related, they like arguing about everything, and both the lead male mostly bullied the girl to get her attention

It could be the blue shorts, but ITSAY gave me Love Sick vibes from the very beginning. Both have that raw, vulnerable, and uncertain feeling that accompanies young love and discovering one’s self. The filter used in ITSAY also imparted a retro feeling that took me back to the early days of Thai BL.

Go Ahead is also a family drama. It has got the same crazy bond between family and siblings. It does not have a mother figure but don't worry Li pa is absolutely amazing mother hen.

Same female lead. Tearjerkers. Movies that explore more than what's on the surface.

About first loves,

Eccentric School Teachers.

Both are underrated romance movies.

if you wanna cry, angry, and wanna kill the main lead for no reason...this drama is the first list to watch. prepare your self, your emotional will be up and down. but no regret for this

similar story, W is korean drama, Game Breaker (Dream breaker) is Chinese remake Movie.
in both Male Leads are super hot, tall, handsome guys ))

So True Beauty Didn’t End Yet but I’m writing this with my knowledge on the webtoon and I’ve watched accidentally in love before [THIS INCLUDES LOTS OF SPOILERS]
Here’s how it’s similar-
~Both Dramas The Male Lead is Admired by others and is very handsome.
~ Both Dramas The Female Lead go through a change
~ Both Dramas The Male Lead falls for the “ugly” side of the girl.
~ Both Drama The Second Male Lead is The Male Lead’s Friend or Ex-friend
~ Both Drama The ML and The SFL is an old family friend.
~ Both Dramas the ML is an Idol or was an idol trainee.
~ Both Dramas are High School/College related.
~ Both are Comedy and Quirky type of shows.
And here’s the difference-
~ AIL’s ML is more outgoing and fun while TB’s ML is more of an introvert and likes to be alone.
~ AIL’s FL tries to become uglier while TB’s FL tries to become prettier.

- it has the female lead who turns ugly for some time.
- both the leads are celebrities
- It also tells about inner beauty and has amazing humour
- the plot is also very similar, but 'love the way u are 'also focuses on the story of the side characters
- they have met before
- the FL has hurt the ML

Similar healing for the male lead with psychological conditions, with help of female lead. Unique love stories, quirky, gripping from start to end.

Both deal with married couples , and one spouse finding out hidden identity of the other, shown in very different ways but similar theme.

This is the original version. This is the Chinese remake of the Korean drama I AM NOT A ROBOT! Literally everything same with just little change!

The love story is just secondary because the sweets is the number one focus.
WwDS is more heavy while KKA is light and fluffy in story. But if you are interested in the food content, then you will definitely enjoy as much as the other one.

Just be careful not to get diabetes :P
