Okay but I can't imagine hualian having fights BUT I can imagine hua cheng sulking over xie lian's careless behaviour towards himself and that makes him mad and yet he'd still act like a lost puppy. Imagine this:
The argument starts small. Hua Cheng is doing his usual thing that is fixing things before Xie Lian even notices, like repairing roof, cleaning the shrine, providing food and having bandages already ready before Xie Lian even realizes he's hurt
And Xie Lian finally sighs and says something like, "San Lang… you dont have to treat me so carefully. I've survived worse than this."
Which is exactly the wrong thing to say to Hua Cheng because to Hua Cheng that sounds like, " I suffered before, so it doesn't matter."
So he just smiles that thin smile and goes, "Gege is right. You've survived much worse." And then he disappears but Hua Cheng is terrible at actually staying away. So he starts lurking. Not in a scary way but In a pathetically obvious ghost king way.
For example, A suspiciously silver butterfly sitting on Xie Lian's sleeve, a gambler in Ghost City staring too hard from the corner, a tall man in red who immediately turns around when Xie Lian looks up.
The man, "…Wrong person."
Xie Lian, "you're wearing your own boots" The man leaves.
It goes on for days. But still every time Xie Lian needs something, it’s already handled. the broken door is fixed overnight medicine left on the table, someone chases away troublemakers before they even get close
Hua Cheng thinks he's being subtle, he is not.
Finally Xie Lian corners him on the paradise manor rooftop
Hua Cheng is leaning on the railing pretending to watch the street like he was there the whole timep
Xie Lian says gently, "San Lang… are you still angry?"
Hua Cheng doesn’t answer for a long time and then he says quietly, "Gege said he's lived through worse."
Silence and then his voice drops, almost bitter, "As if that makes it acceptable."
Xie Lian tries to respond, but Hua Cheng cuts in. For once he actually sounds… upset.
"You've had it worse. I know that." He finally looks at him, "Which is exactly why I want to take care of you now."
"Just because you suffered before doesn't mean you deserve to keep suffering."
And suddenly the whole argument collapses because Xie Lian realizes that hua cheng wasn't trying to protect xie lian. Hua cheng knows xie lian is more than capable of protecting himself. He was js trying to give him a life where he didn’t have to endure things alone anymore.
Xie Lian sighs, a little helpless, and says: "San Lang… you realize I wasn't rejecting you, right?"
Hua Cheng mutters, "It sounded like you were."
Then after a pause, he continues, "Also you almost fell off a roof yesterday."
Xie Lian blinks,"You were watching that?"
"Of course I was watching that."
