It's not really Seyeong's fault that the staff dropped in value right after he sold it to her tho *shrugs*

I don't understand why she's out for blood when it comes to him. Honestly, I wish Yoona would be besties with Seyeong instead (because we love supportive women in BL) but from what we've seen so far from her there's no way in heck that the plot would go to that direction.
