Since the Grand Princess felt that she could handle this matter entirely on her own and had no intention of letting Uchiha Hiko intervene, he felt that since they each had their own ideas, there was no need for him to meddle further.
After all, this was merely a matter between their family members. If an outsider stepped in, it might only make things more difficult. Uchiha Hiko did not want to make things awkward either, so he decided it would be better to stand by and do nothing.
"As long as you know where to draw the line, that's enough. I'm only worried because you're too kind and easily bullied. But when it comes to matters like this, you mustn't let yourself suffer. You need to have your own measure in your heart."
"Although I haven't had much contact with the Second Princess, I more or less understand her temperament by now. She can be reckless at times, and you don't want to stoop to her level. So if you don't wish to say much, there's no need to keep talking to her."
"I'm only worried about you, which is why I can't put my mind at ease and wanted to intervene. But now that you've made it so clear that you don't want me involved, perhaps you simply don't want to drag me into this."
Although Uchiha Hiko was no longer intervening in the matter, he still wanted to make things clear with the Grand Princess, because he could not help but worry about her.
However, Uchiha Hiko was very aware of his place in this matter. He knew he was merely an outsider and had no right to interfere. If he insisted on meddling, then if Your Majesty the Queen found out, she might even blame him.
