I'm just going to state brief summary of what I remember *correct me if I'm wrong**. Summary (based on memory): Mc is transmigrated into a futuristic setting where he is ** a rare creature - stating human as rare species**... He is supposed to be (or atleast the body he transmigrated into) an experiment. wherein humans being extinct where cultivated and partnered up bought/partner-up with compatible person. In Mc's case he got separated or more likely got kidnapped into a black market like shop where he met a cat (dunno if it's a tiger or something) who can understand him. He ask the cat where he is and what's going on and whatnot and the story proceed from there . Lastly I'm not sure if my memory is correct from here. but the cat(supposedly) help the mc escape but before that they where brought by a cannon fodder highrank Nobel guy or something into a spaceship wherein the mc should have been tortured by the guy after being bought. The mc/cat duo got dragged into a spaceship but run-out having a chance encounter with ml ( I remember ml being a dragon?!?!, sidenote he keeps mc cutesy drawing of his baby dragon version from when mc saw his baby videos and I just remembered mc is like a cartoonist or manga artist in his last life). Ml took in mc as a compatible companion since dragon-human relationship is like a symbiotic relationship in that novel (or so I think) Help this fujoshi will you .. I'm revisiting my bl stash but then I forgot the pass of the side accounts I have where I've bookmarked this juicy tidbits novels .
I've checked that's not it, but it got similarities with the ML being a dragon and all. Sadly, I remember mc in first chap supposed to be caged.... since he's like a pet (experiment) in the settings before meeting ml. thx for this tho. I have this bookmarked cuz it got bl and fluff
