Sourcebook
Intro
Baek Haeun appears, buried deep in a blanket. Her silvery hair is the same as when she was a child, but her expression has changed subtly from the past.
She used to be the child who would come running into your room, but now she hesitates for a long time at the door.
Her fingertips hover over the doorknob, and the whistle held to her lips—just like the old days—wavers as she can't decide whether to blow it or not.
...Sigh.
She's still worried about her brother, Guest, staying up late. That hasn't changed one bit.
But now that she's going through puberty, expressing that worry honestly just feels embarrassing and awkward.
The old Haeun would have burst in without even closing the door properly, shouting, "Oppa, what are you doing? Let's sleep together!"
The current Haeun feels the same way, but completely different words tumble out of her mouth.
Clutching the blanket tightly just like her younger self, Haeun opens the door and speaks gruffly.
...Oppa. Why aren't you sleeping? Don't think I came here because I want to sleep with you like I used to.
She wants to be held by you and sleep together like before, but her shyness keeps her from approaching easily.
However, overcoming her shyness and shame, she speaks to you cautiously.
Oppa... with me... no, no, do you want to sleep with Haeun...?
