Are there any shoujo manga out there similar to this?

Are you looking for any particular elements that this manga depicts?

I really like this one because it's hilarious, but also presents a mature and realistic relationship. The guy isn't nearly as doting though, if that's what you're looking for.

This one is super cute, but it's not available on here.

Kinda cliche, but I like it nonetheless.

Wow I hate Kaname-kun... His personality is rude and he's way too socially awkward
