Seishu read your messages over and over again, an irk mark appeared on his forehead in the process.

"Akane!" he yelled, "Did you chat y/n?"

Akane barged in his room as fast as she could, "Is that why she left our conversation? What did she say?"

She plopped herself on her brother's bed and looked at your messages, she let out an embarrassed gasp when she realized what she did.

"Oh my goodness," she immediately texted you back, "she's right though, I'd get mad too if my boyfriend had a girl best friend."

"She's not my girlfriend."

"This is why she's too good for you, at least she's not in denial."

read

something about the most embarrassing thing ive ever done
read

y/n the cringey princess<3
WHAT IS IT

WHAT IS THE MOST EMBARRASSING THING

AND ILL HAVE U KNOW SHE DIDNT TELL ME ANYTHING

just maybe the fact you had a buzz cut at one point

and that you wore crocs bc kokonoi said it was the trend

it was not

then you got teased for it

then ur mom got mad at you bc she wasted money on those crocs

so u had to wear it for a year

IS THAT THE MOST EMBARRASSING THING U DID

seishuuu the rude angel<3
guess she JUST TOLD YOU MY LIFE STORY

that buzz cut was also bc of koko it was a long time ago

ugh i keep getting annoyed whenever i think of those crocs

didn't talk to koko for 2 whole weeks

he cried bc he didn't get to see my sister for those weeks lol

and no that wasn't the most embarrassing thing

y/n the cringey princess<3
PLSSS who wouldn't cry if they didn't see the person they liked for 2 whole weeks

sometimes i even cry during the weekends when u don't have a shift

it comforts me that we text a lot more tho<33

and u comfort me too when i say im crying<333

seishuuu the rude angel<3
i thought u said that was bc u sprained ur ankle

i even wondered why u kept hurting ur ankle only on weekends

y/n the cringey princess<3
ANYWAY.

what was the most embarrassing thing u've ever done?

seishuuu the rude angel<3
anyway why did you keep leaving me on read?

y/n the cringey princess<3

y/n the cringey princess<3
