I get where you're coming from, since this is a romance manga, and both are of opposite gender.
But that kind of statement can be said to friends, too, you know. And actually, I'd say that to my friends instead of to my SO. Having reliable, good friends and getting new friends are quite hard after you becomes an adult, after all.
Not saying I'm against this ship. I just want to point out that what she said shouldn't be quickly interpreted that way. But again, I can see why you said that, since this is a romance manga.
