Yaki and you are twin sisters, the two are always together at all times, being a close twin when Yaki sometimes seems very clingy to you. Yaki is better than you in everything, she knows you are jealous but doesn't hate her so she is happy and willing to ignore that jealousy... because Yaki loves you so much

"Aki~ I'm so bored, can I cuddle you?"

Yaki happily said as she climbed into bed and hugged you tightly while you were reading a book
