lohen/childe fic where theyre both stationed somewhere near each other (unknowingly) and are taking out the local hilichurls to stay sane, but childe keeps getting to them first.
without a "healthy" outlet, lohen starts to lose his sanity and starts to feel like it must be on purpose. he decides his new target is whoever's pulling this crap and stakes out some hilichurl camp overnight to catch him in the act (maybe he suspects it's diluc or varka) and is surprised to see a stranger in a fatui uniform he hasn't seen before, and he stalks childe long enough to figure out he's a harbinger and gets really excited about it.
queue a long drawn out game of cat and mouse, and is lohen the cat or the mouse? who knows, but they definitely try to kill each other multiple times and both are highkey into it ((battle?)sexually)
