What happens when Yeojin starts puberty?
im assuming youre talking about this au (that extends into this olivia centric drabble)

Yeojin knew it was coming, she was nearly eighteen years old already, and her alpha hormones were slowly building up to it's youthful peak. She's quite afraid of what's in store for her - knowing how hard it was for Hyejoo, - she knew first hand, afterall - but it didn't stop Yeojin from feeling kind of excited.
Puberty was known for it's growth spurts and roller-coaster-like emotions, the youngest alpha in the house was only looking forward to the former. Maybe she'd finally outgrow all her unnies - Hyejoo wouldn't call her 'minion' anymore.
Sooyoung had given her a few tips on how to deal with the pain and emotions of the first few days of puberty - scientifically proved the worse ones - but Yeojin didn't quite listen to her unnie, thinking they were all exagerating.
Just, they weren't.
The first night was hell. Yeojin's whole body hurt much she couldn't walk out bed, staying all of the following day on bed. Day three was extremely overwhelming. Living in a house with six omegas proved itself torture when suddenly she could smell everyone's - even the alphas' - scents as if they were all inside her room.
It was a busy week in the dorms, so until the fourth day, no one noticed, or had time to do anything about it, until Haseul knocked slightly on the youngest's door. The lack of a response at 4PM alarmed even Sooyoung, who was watching the omega few feet away. Eventually the couple found the young alpha tearing up a little on the bed, her whole body hurting from the puberty's merciless, constant changes on her body.
At first, Haseul felt like she failed with the younger - she knew how stubborn Yeojin could be, but didn't try keep her in check with the pain suppressants Sooyoung suggested, because of her busy working schedule.
"It's becoming more bearable, isn't it?" The second oldest alpha asks, coming in just after Haseul, a hand on her hips to keep her safe and close. Just in case.
"Yeah," The other alpha meows, crinkling her nose at the strong omega scent of Haseul. "It's better than the other three days."
Sooyoung thinks for a second, "In this case it's not even worth it taking the pills then. It will die out in a few hours..."
The oldest omega was still worried, though, chosing to pat Yeojin in the head while reprimanding her slightly. "If you weren't so stubborn, Yeojinie! You were all this pain for days..."
The blonde alpha smiles a bit, pain still present but slowly being forgotten due to the relaxing presence of the parent-like duo in front of her.
"It's okay! I'm getting better already, unnie!"
Sooyoung is convincend by the words, but still keeps an eye open for the rest of the day and several upcoming ones - she knew it was just the start of the emotional roller-coaster they've experienced with Hyejoo and even Hyunjin already.

When an alpha hits puberty, their body changes and grows either in size, getting taller and "more tough, alpha looking" or just enhancing their strength, protective instinct and dexterity. Through the weeks, Yeojin didn't grow much taller, just a few centimeters, and instead became the fastest alpha of the pack. (She also developed a few other lupine abilities eventually)
