Relationships are not good.
It could be a personal grudge, or a public feud.
Zheng Qing always considers himself to be kind-hearted, rarely initiating arguments or conflicts at school.
Strictly speaking, he only had a fight with Arthur·Ness when he first entered the academy, ran into disputes with the Fishmen of Lin Zhong Lake, and accidentally injured Sepulano badly—if conflicts aren't limited to student status, he also had a brief dispute with Professor Trudeau from the 2006-2008 Great Arcana Sequence's 'World'.
Apart from that, he dare to swear with Furry Bean's paw that he has no other personal grudges.
As for those who secretly stick little grass figures or draw circles to curse him, join bonfire parades shouting 'Burn Zheng Qing', send him explosion charms and roaring letters, and those who frequently come knocking to challenge him to duels, they all fall under 'public grudges' in Zheng Qing's mind.
