[ His letter... she's touched by the care contained in it, as well as the gifts. They bring a warm smile to her face, her heart swelling with fondness for this person who has taught her so much and shown her so much kindness. If nothing else, she's so happy to be his friend.
Since letters are actually the preferred method of communication where she's from, she doesn't hesitate to write one back. Maybe it's not surprising, but she's much better at writing letters than talking out loud. ]
Setsuna—
Thank you so much for the gift, and for the map too. I think this will definitely come in handy!
I'm really happy that you were thinking of me. In truth, I should be the one thanking you for everything you do for me. You've always shown me such kindness, and I've learned so much from everything you've taught me. I'm so grateful that I had the chance to meet you here.
I know it's not much, but I want you to know I'm here for you too. I hope you can rely on me.
