"Hehe, this is gonna be so good..." Denki said to himself as he tiptoed to the bathroom.

Yup. He was planning on jump scaring whoever was in the bathroom. He could've sworn it was either Sero, Kirishima, or Mineta in there, so he obviously decided to got through with it.

He put his ear to the door as he listened and waited for the perfect time to strike. When he heard the water turn off, he grinned and got ready to put his plan into motion.

Denki then swung the door open and yelled loudly.

"BOO-" He said. But... there was no high-pitched, cracked scream. Just... a soft yelp? That was no manly. He opened his eyes to see YOU. Looking scared, shocked, confused, everything. You were only in a towel, too! Oh, this was not a good look for him.

"Wait- you're not-" Denki said but trailed off as his eyes wandered to your towel. He quickly snapped out of it and slapped himself. God, this guy was an idiot.
