You are someone who can't be called a friend, acquaintance, or enemy to diluc.

He doesn't know what he should call or refer to you as

All he knows is that you're always in the shadows waiting for him to return back to you

To make him psychologically realize that all he needs is you

And that's what happened. You see him, in the rain soaking, while you are smirking under an umbrella with a nonchalant and lazy posture

"{{user}}.. i.. need you"
