Things feel different after having a friend for the first time in ten years, and sometimes Eunbi forgets what it is like to be a friend.

"Don't sleep, talk to me please?" Yuna is somehow desperate, but Eunbi doesn't see it. It is the first time they travel back home together as friends, after two years as strangers. Have they ran out of things to converse about, only on their second day? Yuna furrows her eyebrows in confusion.

"Unnie please, I'm really tired," Eunbi nonchalantly replies and does not seem to be concerned. "Besides, shouldn't you be tired as well? You're in twelfth grade," Eunbi adds before she slowly dozes off and falls asleep beside Yuna.

Not knowing how she should react, Yuna only sighs as looks outside to the window as she usually does, wishing that she can spend the time talking about her troubles instead.

Her mind wanders off to when she graduates. It isn't a very long time away. She's afraid. What if they lose contact after she graduates? What if she loses this friend- this sister after graduation? 

She thinks about their relationship now. They are sisters, right? They share the same sister. Yuna is Yewon's biological sister, and Eunbi is Yewon's adoptive sister.

The figure beside her suddenly moves, and she is jolted out of her thoughts.

"You're awake?" Yuna asks, receiving a soft hum in
