Makjang dramas that are all about revenge and betrayal. Both FL of this drama have a comatose and lose their memories while the SFL steals their man and marries them. The FL of this drama seeks revenge. Both ending have the FL choose the ML even if he's not worth it.

I was missing The whirlwind girl so bad.. After watching falling into your smile.. it reminded me of TWG .. Chang 's stone face reminded me of Ruo bai. Both drama genres are same. Game, competition, romance, friendship. You can also see cute and handsome faces in both dramas.

A cute little girl with a lot of handsome boys around...
Both dramas are about friends, games ,romance and their adventure .

Both Forever Love and Lovely Us start from school days. Lovely Us captures a couple of years while Forever love goes further into the future. Both are about the relationships that we form as young adults becoming the defining relationships of our life. Because they are the relationships based on pure non-judgmental love.

Dont Say No seems to be based on the side couple from TharnType2: 7 Years of Love, and the ship is maintained so if you want to see more of them you can find them in DSN

Both films have a similar sense of humour. Extreme job is less serious but continues the theme of crime.

They both are Swim team Dramas, however the ''movie'' was a older version lets call it the original, and ''water boyy'' is a updated version, Now my opinion is that the characters were great and the chemistry was well scripted and the actors did a great job of conveying there character as if they were real people . A much more comedic feel that you can get that feel good factor while just engaging in the plot and letting it all sink in.

Both have different/mini stories in them with a similar theme of people having an agenda, which may cause them to have consequences for their actions.

It looks like Song Sanaeha, another Ch 3 trainwreck, manages to be even more controversial and traumatic than PRPK. Take this as a warning or a recommendation, depending on your pain tolerance.

They might be not that similar in plot and story, but have a similar feel to them.
There are many crazy/funny moments in both on the one hand, and at times they get really dark and thrilling on the other hand.
In both dramas the main antagonist is a psychopath.
And in both there are some funny scenes with gangsters, who look tough at first, but turn out to be softies actually and respect the main characters (ML from PD, and FL from SWDBS), after they get beaten by them.

If you want a lakorn with a ton of kissing, real kisses, and the couples mostly fail at hiding their feelings, both of these are a good fit. Both also have a distrusting ML who doubts the FL's character, but still can't stay away.

Both contain elements of religion and a sort of demon/illness; also focus on exorcising. Both films cinematography captures and enhancing the storyline.

I think they both have something in common,
The ML is weak at first then later on turns out to be the big thing.

they have the same actors in both bl dramas, Jumpol Adulkittiporn aka off and Atthaphan Phunsawat aka gun. They are also both the couples in the bl's. and basically they are both bl dramas
