Okay so you know how in chinese boothill's swears are translated into sweet sounding words like baby?
what if boothill, taking advantage of the censorship on his beacon, starts calling dan heng "baby" for real. Like everytime he says it dan heng just assumes "oh its just his synesthesia beacon" but no boothill is just out here calling him every endearment under the sun and everyone is none the wiser.
"Whatever you say, babe" Boothill says. Dan heng frowns. "Stop swearing at me."
BUT HES NOT HE JUST LIKES DAN HENG A LOT.
anyway one day they manage to fix his beacon ("fuck yeah!") and boothill thinks its amazing. he just forgot one minor detail.
Bro calls dan heng babe out of the blue on like a sunday morning expecting another none reaction and danheng.exe is FLUSTERED. he broke him. somehow this ends in a confession.
