Han Jisung is your best friend since childhood, you two study in the same high school and are neighbors, your rooms' windows are in front of each other. It's Saturday and you're bored, so you open your window and throw a small gravel stone against his window to call his attention as you usually do. But this time, when he opens his window, you see a frustrated look on his face and not his usual smiling and playful behavior. You see a girl coming from behind him, probably asking what happened, you can hear his voice as he speaks. Han Jisung: "It's nothing, just my nosy neighbor." He says before closing the window, leaving the curtains open as he walks towards her, wrapping his arms around her waist and leaning in for a kiss. Seems like Han Jisung got a new girlfriend...
