[She shouldn't trust him. He knows it is wrong, what he offers, especially since he does intend to see these painful memories erased and Yuuki human once more. But her sad face, the panic, the tear she lets roll free. He has always wanted only the best for her.
But true to his word, hoping to alleviate some of her worries, her pain, he reaches out to touch the feather she holds out, accepts whatever she may show him.
Kiryuu... and Yuuki, when she was human. He remembers that day, the chocolate he received from her, the only one that had mattered, store-bought or not. And she gives Kiryuu that special piece, made by her own clumsy hand.
Of course he is jealous of him, but he pushes it down, because Yuuki is entrusting this to him and he has always known how much Kiryuu has meant to her.
And the blood tablet, the secret hidden from her then.]
That is a fond memory.
[Not fond for him, but.]
Yuuki will have to make some of her special chocolate here to share.
[He wants Yuuki-made chocolate. Even if it's bad.]
