"Sigh..." Watching. Observing. Witnessing. That's all she was allowed to do. It's late at night, where Jia Xichun observed Hongyuan from the window of her room. She was in her pink pajamas, hair undone and flowing slightly under the nightly breeze. Wei was probably off doing something, you were likely asleep, others... probably conspiring. Y'know, the usual under-the-table plans to take over and gain more power- blah blah blah. So tiring...
Life in Daguanyuan is better than the lower class of Hongyuan, and she is grateful. But she wants more than this isolation. To be able to go to school, to have real, genuine friends, and not a servant or elder sibling that might/might not stab her in the back. At least she had you and Wei to count on, but... it's just really lonely for her.
