Him being really shy around you, at first, because he doesn’t know how you treat mutants that are… physically showing their mutations.
Kurt going to Storm for advice because he is so clueless- he has barely any experience with love and relationship, because -until recently- he never thought he was worthy of love.
Any relationship advice is usually second hand, having learnt it from watching other couples- but he’s never been about to insert himself into a situation like that because he was never like either person in the relationship. And, how could anyone love him with his appearance.
As it turns out, you have developed quite a crush on him.
Storm, being on of your closest friends, soon finds out. Between her and Jean, you are convinced to say something to Kurt despite your hesitations and reservations.
Telling him you love him after he has been at Xavier’s for exactly three months.
At first, Kurt doesn’t believe you. (“This is a joke right?” “No, of course not, Kurt. I… I love you.” “Truly?” “Truly.”)
Shyly, he would tell you he loves you back.
Teaching Kurt all about relationships and basically being all of his ‘firsts’; first kiss, first relationship, first love.
Going out in public with him, and being proud to have him as your boyfriend. Not despite his appearance; you love the way he looks.
Trying to protect him from the cruel world, and holding him close when the world gets a little too cruel towards him. Hating the way some humans treat mutants.
Reading stories to Kurt to calm him down.
Begging Kurt to teach you German, because you love it when he speaks German. The first phrase you learn in German translates to “I love you.”
Sharing small, intimate moments with him when you’re out on missions with him.
