a/n: because today is 7 days after Nayoung's actual birthday and 7 days before Sowon's!! kids turning 22 this year eue

(Nayoung/Sowon: 15)

"Happy birthday hate" writes a simple post it on the alarm clock besides Sojung's bed.

Sojung realises only after checking the time. She does not look at the clock while turning the alarm off. (She's given the responsibility of waking the older twin up because obviously it won't work out the other way round- it never has.)

Chuckling, she glances over at the older twin who has the sheets tightly wrapped around her, covering even her head. Sojung knows she's pretending to be asleep so she wakes up and walks to the table, gets a pen and post it and writes a short note (which turns out to be way longer than expected).

Sojung shuffles her feet in her slippers as she made her way to Nayoung's mobile phone that is on her bedside table and pastes it on the screen.

Nayoung tenses up as she feels Sojung's presence right in front of her. Waiting silently for Sojung to exit the room, she hides under the sheets anxiously.

Once she hears the door close, she shoots up from the bed and turns to her bedside table.

"Happy birthday you of an unnie. You're two minutes older but two worlds apart ie stupid."

She releases a loud grunt and exits the room, ready to kill.

"Kim Sojung, come back here!" she hollers and wakes the whole house up.

"Happy birthday you !" Sojung doe
