He smiled a little, while Ren was just in Katsuki's bedroom, sitting on a chair. Reading.
Peter walked past the open door
"Ughh- Katsuki only has boring books-"
Peter could hear Ren.
Peter poked his head in
"You could go to the library-that's where I'm going-"
"AH-"
He jumped in his seat, startled.
"Oh! S-Shoot, I'm sorry are you alright!?"
"Yeah- I-I'm fine- you just scared me-"
He was breathing heavily- PETER THATS WHY YOU DON'T JUST POP OUT OF NO WHERE-
"Ah-sorry, sorry-I have a really bad habit of sneaking up on people-"
"It's fine just please- pretty please- don't do that again to me- my nerves are always high- and I get scared easily-"
He nodded
"Mhm-I promise it won't happen again!!"
