mitsuki asking katsuki if he made any new friends every single day, since he began high school in ua, just to tease him.

she wasn't really expecting much, especially since katsuki started shouting, "no!" as soon as he opened the door to their home.

so it was definitely a surprise when he reverted back to saying, "i'm home."

mitsuki had to drop everything she was doing to rush to the front door to question him, "you made a friend?" she asked.

katsuki only hummed in response. she didn't pester him further.

a few weeks of "i'm home"s later, mitsuki found herself opening the door to a redhead.

"hello, um... is this the bakugou residence?"

"yes, it is. you are?"

"i'm kirishima eijirou, ba- katsuki's frie- ah- classmate?"

the kirishima boy ended up picking katsuki up for a class gathering after he apparently refused over text multiple times. since when did katsuki text anyone?

when katsuki got home that day, mitsuki was ready to annoy him with questions about kirishima.

"was he the friend?"

a groan. "shut up, hag."

"he called you his friend, you know."

that made katsuki stop and look at her with wide eyes. "he did?"

mitsuki shrugged. "kinda. he cut himself off and said classmate instead. probably thought you didn't think of him as your friend."

katsuki just frowned, as if in deep thought, before stomping upstairs.
