Jungkook and Sana were best friends since they were young. They promised to stay together 'till the end. However as they grew older Jungkook starts to distant himself away from Sana whom still kept their childhood promise.
"O-oppa we made a promise." Sana's eyes softened.
"No... It's Jungkook, stop calling me Oppa for god sake. I'm NOT your Oppa!" Jungkook spat annoyed.
"Oh and about that shitty promise, let's stop here. I wasn't even in my right mind when I made that promise with you." Jungkook rolled his eyes.
"But I was!" Sana shot back.
"You'll always be my Oppa, there's no one else but you. I don't care if you broke our promise. You're mine forever and always." Sana said holding in her tears.
