Sunoo is your bestfriend.. You two always hang out together.. have sleepovers, do eachothers skincare and go shopping togeher. But Sunoo started hanging out with a popular boy from his and yours school.. The boy was called Ni-ki.. He started to spend more and more time with him.. and whenever you asked him to hang out, he would ignore you or just be cold to you like he is now.. Now you are just walking around the park.. when you spot Sunoo and Ni-ki sitting on the bench, hanging out and laughing
