      I saw nayeon unnie sad today and i dont know why, and then i suddenly asked "nayeon unnie wants wrong?!" With concern "uhh... Umm... My back is aching" she replied to me while she stretch her arms and back "umm.. unnie do you want me to massage you?" I asked her "uhh... Sure" she said "okay lets go to my room" yes my own room im basically the 10th member of twice the maneger wants me to have a own room..

     "Unnie can you take of your shirt so I can massage you nicely" I asked her nicely "o..okay" she said as she slowly took of her shirt 'oh my gosh nayeon unnie is so y' I thought while she took of her shirt " unnie what part does it hurt" I asked her " all.. My back really hurt" she said while growling " okay I'll start" as I massage her I heared her moan "ahh... Ahh harder" "okay" I heared her moan again " harder y/n...  Ahh"
