"Your guess is correct." As thoughts spun in his mind, Ian nodded. Although he wanted to tell Yisen, 'I've indeed used the Foresight View to prophesy every time I brewed a potion,' he ultimately agreed with Yisen's guess directly: "In fact, I've always been wondering when you'll notice something off about me... When you'll realize and understand, it will prove that you've truly grown to the point of knowing."
"Yisen, you were a bit naive and hasty back then, so I didn't dare tell you the truth. Master Gossay also chose not to say much to protect you, hoping you'd understand."
"But now."
Saying this, the young man smiled brightly: "You've grown, my friend. Now, I can trust that you can keep my secret!"
"...Of course, I understand. Even if you kept this secret from me for a lifetime, I would completely understand."
Raising his head, Yisen Gard solemnly vowed in a way unexpected to Ian: "I will guard this secret until the end of my life!"
