Well, it's a Shojo manga in the end. But having said that, I think it's pretty obvious they are going to do it soon. It's even heavily hinted at near the end when they have their talk about Haruna not wanting to go home.
like all the shojo... It's my fault for hoping every time that it would happen... now, I have to go back to yaoi to recover (however, this was a good story ٩(๑❛ᴗ❛๑)۶)
They never had "that" moment. . .
