Unlike the last time, Himuro states her feelings matter-of-factly. Yukimura asks, "What theory did you use to determine that you love me?"

so that I can determine 
whether or not I love you.

ob ich dich liebe oder nicht.

si je t’aime ou pas.

se gosto ou não de você.
чтобы сделать вывод о том,
люблю ли я тебя.
