The man asked, puzzled, "What does this have to do with the theme of the ball?"

Chuanliu showed the slightly smudged handwriting on the invitation: "If ink gets on your hands, it will take at least a day to wash off. You have done your best to deal with it, but because everyone's faces are covered, I have been paying more attention to everyone's hands."

Since you've chosen such a nostalgic method as using a fountain pen, envelope, and handwriting, you shouldn't deign to have someone else write it for you.

"You agree, don't you, Miss 'Nine of Diamonds'?"

Chuanliu spoke slowly and deliberately, until the last sentence, when he turned his gaze back to the woman who had remained silent.

The woman raised her head, her previously timid eyes now bright and alert. She casually tossed the ends of her curly hair and tapped the table with her finger.

The man immediately understood and poured her another glass of red wine.

"Is that all?"

No longer the same shrill voice from this morning; the woman has a cute, childlike appearance, but exudes a mature, sophisticated aura.

Chuanliu shrugged. “If you look at your interactions using this assumption, the details become much clearer. For example, when you two are together, he’s always the one walking towards you; or if something happens that you haven’t told him to do beforehand, he’ll always glance at you before he speaks; or if a cup just broke and you didn’t care about his hand, or even think about wiping it for him.”

Therefore, the man who always shows his face is nothing more than a puppet of the real "Nine of Diamonds".

The woman's gaze shifted from inquiry to understanding. "I was wondering how you, a new resident, managed to retain the identity of 'Square 3'. Now it seems that your position in Mahu is a bit of a waste of your talents."

Let me reintroduce myself. I am the real Xu Zhi—"Square 9".
