It's a fantasy martial arts style. The protagonist has been very arrogant since he was growing up. He has a domineering system. It's almost a filter effect to think he's cute! Don't think that just because he's handsome, he's reliable!
The trend is basically:
I wanted to protect my sister, but I was protected by her.
I wanted to protect my junior brother, but I was protected by my junior brother.
Wanting to protect Xiao Gong, Xiao Gong chuckled and showed his charming [? Weak? Smile: Ah Jiang, come and protect me~ Come on~ Come on~~~
Ren Jiang burst into tears! Hero! This script is wrong!
