こんにちわ,
konnichi wa, Yuna-san.
I wanted to extend an invitation to you personally to attend my wedding. The adamantium has not killed me, and though I am very weak, I will continue on. But my gentleman friend has asked me to marry him, and I have accepted.
Both in the name of friendship, and the wish to show you a Japanese bride, suggest that I extend the invitation. I would like to see you there.
I will provide a specific date when we choose one, but it shall likely be after the winter holidays. But you have shown me kindness, and I wanted to be certain you were aware that your presence was wanted.
Yuriko
