Which pairs match each other's vibes perfectly?

They match each other's freak to a degree that is dangerous to the public

Okay friends, which pairs (or groups) fit this description?

I saw this was like, yes A'Li and Xiao Heng (The Double) definitely fit this so much! I love their wild and slightly unhinged desire for revenge.

Gong Shang Jue and Shangguan Qian (My Journey to You) - the couple who's chemistry is off the chart. They're dark, they're manipulative, they're gorgeous. They match each other's vibe to a T.

Yuan Shuai and Jiang Jun (Love is Sweet) and their ridiculous sass.

Bai Ju and Ying Lei (Fangs of Fortune) - their adorable chaotic little brother vibes is perfection. You know together they are a menace to the public when they're together.
