haiqiang
A haiqiang is like that one person who's always quiet, but when they're with you, they're the loudest person in the room. They don't show their feelings until you're already halfway through your own breakdown.
"You didn't say anything until I was already crying."
"You're the loudest person in the room when we're together."
"You showed up at my house in the middle of the night just to yell at me for being a crybaby."
