Both are japanese rom-com dramas about single president of the company in his thirties. They also give off similar vibes.

In both dramas the hero likes the heroine first and in both their struggle to win her over is really entertaining to watch. They're also workplace dramas and have a similar feel

The plot lines for these films are very similar; a normal high school girl gets prettier as the film progresses in order to grab the attention of the most popular guy in school.
Cute, sweet but cliche.

Similar plot line. the father has an affair and as an act of revenge the woman switches the child, then neglects the child she took but the child grows up a bright child.

nirvana in fire and battle of changsha have that kind of masterpiece vibe , if you liked nirvana in fire you would definitly enjoy battle of changsha
- light sweet romance exists in both dramas.
- issues of politics and war exists in both dramas, battle of changsha looks more real and honest, it has no fiction, whereas in nirvana there are some fictitious events.

If you like mystery/thriller.... Balanced with a bickering romance and comedy.... The plot is amazing....

Great music as well.. You will enjoy it for sure, if you just focus watching it....

same feel of comedy and directing style
