This is a gift, so if there's any way you'd be willing to slip a gift note in there for me, I'd be very grateful :) I'm sorry if there's a gift option and I missed it! "Happy (possibly very early?) birthday! This gift shipped from Japan so I was scared it would be late if I waited too long! Maybe I'll get one too and we can be pen pals again like when we were kids.
ギフトオプションをもし私が見逃していたならすみません!「お誕生日(早すぎ?)おめでとう!このプレゼントは日本からの発送なので、遅れてしまうのが怖くて!自分用にもひとつ買って、子どものころのようにまたペンパルになれるかな。
