friend? FRIEND?
is this what the subtext tag means?
the most homosexual moment of two girls' lives (to this point) ends with "and that's why we're closer friends now."
Nagi is totally in lesbians with Airi, but her head hasn't clocked in on the fact that she's gay yet, so she's trying to label their relationship with whatever she has available.
Normally I'd say there's still room for her to be a very clingy, codependent friend, but "I wish we could merge into one person" kind of eliminates that. That's not language you use in that kind of context.
