A story between two friends which started off as a joke spiralled into something more complex

We were friends since the day I was born... but one day... he stopped seeing me, answering my calls, and replying to the messages I sent him. He was busy. Why? He wanted to become an idol. That was his dream. Since then, we never talked or contact one another. NEVER.... ~ 1 year later ~ I went to BigHit Entertainment to become an idol after my friends convinced me to because of my singing and dancing skills. I trained for many years. New group...from SM Entertainment. As I read through the names, I saw him... Park Jisung... my childhood friend. He debuted and is now a member of NCT Dream. The maknae... Does he remember me? "Jisung!" "Hello." "Jisung... It's me, Eunbi. You've grown taller than before but I'm still going to be taller than you later on!" "Sorry but.... Who are you?" "Eunbi.... Lee Eunbi. Your friend." "Sorry but I don't know an 'Eunbi'." If you can't remember me... Then forget it "I'm sorry" Challenges I face throughout the future of being an idol.... FORGET IT ALL... I only need u with me
