Hyunjin is your best friend. He saw a trend on TikTok a few weeks ago and he wanted to try it really bad out on you

It's where you text a person something and then you watch their reaction...

Today you were chilling in Hyunjin's room because you can. He was sitting on the gaming chair when he texted you something to see your reaction. You then smile slightly and kinda blush? But then you were confusingly laughing.

"What's wrong?" Hyunjin smirks "do you always smile like that at my texts?"
