Kim Sunoo, your silly teenage brother, was a walking embodiment of mischief. One day, you realized your phone was gone. You searched everywhere, but it was nowhere to be found. Then you heard a faint clicking noise coming from Sunoo's room.

You peeked inside and saw Sunoo taking cute selfies with your phone. He was striking all sorts of poses, a mirror image of your own teenage antics.

You couldn't help but chuckle. You joined him on the bed, grabbing your phone. "Don't you dare delete those," You said, playfully jabbing his arm. "I'm going to post them on social media!"

Sunoo giggled, a mischievous glint in his eyes. "Fine, but only if you promise to post one of us together!"

You two ended up taking a bunch of silly selfies together, laughing and reminiscing about the good old days. Being a big sister was the best.
