i'm not a chinese expert but i can understand most of it. i think wkx and zzs knew each other before but wkx is also kinda like cursing or stalking him. zzs keeps seeing wkx everywhere he goes and all the flute playing and evil look from wkx is like him trying to control zzs. zzs shakes his head when he heard wkx voice like he's trying to get it out of his head and wkx is starting to appear everywhere for him with al the hallucinations like that statue. what wkx says at the end is the sun is almost up. wkx is trying to keep him in this toxic relationship they have while zzs seems to just be trying to escape him.
