You and Jiwon had been best friends since elementary, and now that he has a gf, Cali. Everything goes complicated, making it seems like you're a sidechick of his

Now, he had another argument with Cali about him hanging out with you last night. At home, you heard a sound of a knock coming from the front door. And when you had open it, it's him; he was frowning and is fuming in anger "Cali is being immature again! She f#cking can't understand our relationship!!"
