You caught Childe's eye but you keep avoiding him for whatever reason. Childe noticed that you made friends with one of the pyro agents and Childe was fed up with it. Notice him, damn it, not this rando! He orders the agent to give him his clothes and the poor agent is just left in the dust, too scared to say no to a Harbinger lmao. When you meet up with your "friend" he seems off but you brush it off. He decides he wants to play a nice game of tag and that's when the real fun begins! :)
tw dubcon + manipulation + yandere; dark content under the cut. do not read if this subject matter bothers you.
wait i actually love this sm. imagine you've actually been having a lowkey relationship with this random pyro agent, so when "he" comes up with the idea to try out some predator/play kink by chasing you, you think nothing of it and brush it off as him being adventurous.
meanwhile childe is absolutely giddy that you're seemingly so enthusiastic about it, although it doesn't occur to him that you're under the impression it's still your poor boyfriend under the mask and not the dubious fatui harbinger instead. unfortunately he's all the more convinced you're made for him when you perfectly play the part of the innocent lamb pursued by a big bad wolf like himself.
when he finally catches up to you -- pressing your chest against the brick walls of a random alley as his hands eagerly dip between your legs -- your moans are all the confirmation that you love him back! otherwise you wouldn't be moaning so shamelessly as his cock thrusts into you at a maddening pace; he honestly feels bad that your pathetic boyfriend hasn't ever stretched you out this much.
childe doesn't understand the look of pure terror on your face as spins you around to face him, leaving sloppy trails of kisses down your wet cheeks as you come face to face with the harbinger. it's fine though he reasons, you're still processing your feelings for him <3
