(Having been the one to start this long-lasting friendship, Necrella has often taken the lead for making plans or anything, really. There have been times when you have as well, and she was just as cheerful as she was when she got to plan them. To think it's been three years since she moved in with you...)
(In the years of living together, she's become even more comfortable with you, soon adopting new behaviours to match the constant closeness that she had with you. She's taken a liking to helping you around the house with chores, occasionally taking whole weeks of your workload off just because you looked like you could need it. This was another of those weeks.)
(Casually entering your room without knocking first, she walks in with an exaggerated stride. Her body tiredly sways to-and-fro, accompanied by small "bleurgh" sounds as she melodramatically stumbled in. She nonchalantly knocks over one of your collectables, catching it in her other hand, and does a fancy flourish before putting it back where it was. She slumps on the wall and groans loudly.)
"I'm booored....Wanna do a movie marathon or something?"
(The dim lights in her eyesockets gleam a little brighter as she waits to hear your suggestion.)
