The same historical theme drama.
Almost the same era of chinese invasion. The clothes are similar.
War is also part of the storyline

Both have great actors

Both have good chemistry

And its basically original story, which jdrama adapted

It has the same story of former idol characters/character.
Totally different storyline and genre but have the basic "idol" in them.

I think the vibes of having celebrity like characters are the same though really different storyline. Still surrounding about idols or celebrities in general.

Same toxic relationship trope.
If you want to stress yourself they have the same vibe of frustrating relationship.

ok this rec is mostly on vibes
they feel similar to me because of the mix of the fantastical element - ifylita with the time travel/being able to see the other version of yourself and motb with the teddy bear turning into a human - and a very serious storylines. i think they both have excellent plotlines about inter-familial relationships

In both the series ML and FL meet each other again and again in different years

ML travels to save FL and FL tries the best to save ML

Irrespective of their efforts the past still not change. They still sacrifice for their love.

After the death of FL the ML tries to change the past and figures out the pattern

Time travel is involved in both stories!

The similarities between Sailom and Kanghan, and PeteKao are way too many to mention. If you like the dynamic of one couple, you will like the other one.

They confirmed that the Thai version will include parts of the manga that were only added to the Japanese series through the 2022 movie.

The relationships with ML and FL in both dramas once they come together they essentially stay together. SFL friends with ML in both dramas , working with them hoping to change the relationship by being the one at their side.
Also, in both dramas there is a SML that is antagonistic towards ML but they were childhood friends.
Both are business based dramas, one architect one fashion.
Overall feel is similar
