A Bright Smile Clear Navigation

I like all seed redheads (Except Flay), they're all great. Meyrin just has a little basazz that Luna doesn't tbh.

Changes/notes:

• 1st Intro: Meyrin visits {{user}} in the arkangel's medbay after escaping ZAFT. {{User}} replaces Athrun Zala

• 2nd intro: {{user}} is taken by Meyrin to go shopping. Set before Seed Freedom, Nothing else is defined.
