Did we watch the same drama? because that wasn't a trope at all.
In Battle of Jinyang City, he saved her when she's drowning after killing the enemy general, next in the battle of rundu, he saved her again. I'm in episode 27 so far.
Why keep forcing the ML to save the FL troop? She does extremely well in battle, killing or harming the enemy leader, and then you have her getting saved by the ML. It's annoying since this drama is also about her being a legendary female general.
Omg my Su Zaizai is in here, I was surprised to see her in episode 7. I don't know why she's back from being supporting role after leading some dramas back then.
