Titania drowsed off due to exhaustion and she couldn't even know what time it is outside since there's no window near her, and the only light inside the prison is coming from the wall lamp beside the guards.
Instead of wasting time banging the cell door, she decided to rest so that she could regain her mana and might be able to escape this place on her own. Though Yijun was worried about her and stayed outside of her cell for the whole day.
When Titania opened her eyes the next day, Yijun quickly got up from sitting on the dirty floor. "Do you feel alright? Do you want to eat something?" She nodded without thinking about her situation because she's still sleepy.
However, this made Yijun thought that maybe she changed her mind and immediately commanded the servants to bring food which they obeyed as soon as possible.
