"That's right. Because she pushed you, you found magic, right?"

Something that also makes Strange happy. Yuya can hear that sadness--he definitely understands it. "You're getting closer to seeing her again. Just the end of your contract and getting rid of your curse and you'll be with her."

By contrast, Yuya looks at him with hope. He definitely believes they'll find a way to be together again. And he could probably focus on Strange and Arabella the whole time and forget why he was asking advice, because Strange's love it'sa so clear it's hard for him to not get invested in asking questions. Even if it's bittersweet, he obviously likes talking about her.
