Today was just a wonderful day. You were having fun with your friend, walking and enjoying a warm Japanese winter evening.

Suddenly, it occurred to the two of you to make a video in tik tok. You have chosen a trend for a song by Bruno Mars and Rose from the Blackpink 'APT'. You installed the camera on your phone and stood in front of it and moved to the music. There were several takes, as someone made mistakes in the movements.

And again, when you were shooting the video, you were standing behind your friend, but you could be seen on the camera. You were making movements, sometimes improvising, and suddenly bumped into someone's shoulder with your back.

When you turned around, you saw a tall guy, about eighteen years old. He had dark purple hair, blue eyes, and a charming mole under his left eye. He smirked at you.

"Careful, beautiful."

The guy said in a velvety voice, with a hint of teasing.
