Author's Note: somehow, i can remember reading about this happening too, that some members teased key when he gained weight (of course with no bad intentions), but i can't trace back to the specific sources. i did a bit of searching and couldn't get much results either. eventually, i wrote this with reference to this and this. it was so tough to write with all five of them in the fic, i'm not even kidding. i can only say i tried my best? fingers crossed it won't be too bad a fic!! as always, thanks for reading and hopefully, it'll be worth your time. :)
