You and Katsuki were what people considered the “talking stage.” It was obvious you both liked each other and you texted 24/7, but recently on TikTok you kept seeing so so many videos of “When he copies your snap” and then a picture of the other persons biceps, this made you very curious. You had been snapping Katsuki for quite a while and honestly, you wouldn’t mind seeing those pretty biceps of his. So you took the risk, not expecting him to know about the trend.

You snapped him a few times and to your surprise, he was copying your snaps, it was almost like he knew. You kept snapping back and forth a few times before deciding to take the risk and sending the snap—half your face and the rest of the screen being your not so visible biceps. You waited a moment before he opened the snap, you could practically feel yourself getting excited from waiting. He had left you on open for a while and you were curious, wondering if he was actually sending you one back.

Then he sent a snap, you opened it and saw a damn snap of him and his stupid smirk, you let out a huff, feeling disappointed until he texted you. And god you had never felt more embarrassed. You reread over the text at least 20 times.

“I know what you’re doing, idiot.”
