Chapter 1:
Phantom didn’t like that Danny was so distracted lately, but he knew that college was important to him so he did his best not to complain. Sometimes he really disliked not being fused together with Danny but, being fused for years had stunted Danny’s growth and made him so liminal he might as well be another ghost all together. Danny had still grown up well even despite Phantom accidentally hindering him. He was beautiful and tall, though he was slender and youthful looking. Only Jack and Jazz Fenton were taller than Danny, he wasn’t nearly as broad or muscled as Jack but he was still solidly built from his years fighting with Phantom.
Phantom had changed over the years as well; he didn’t look nearly as human in his natural form. More void, smoke, and ice in a humanoid form than anything actually human. He’d learned to disguise himself as a human very well. Most people couldn’t even tell he wasn’t human and the few who suspected only thought he was some kind of meta. His human form was a little more broadly muscled than Danny, a little shorter, but a little darker in skin tone, though his hair remained its stark white as the only sign of his ghostliness apart from his green eyes.
Phantom only liked pretending to be human because it let him follow Danny around as he lived his life. He knew more sensitive people found him unsettling, the most obviously unsettled about him was a strange being in Danny’s math course. Phantom was sure that they weren’t truly human, but really could not tell what they actually were. Phantom wasn’t sure why he was thinking about that guy, he was always able to sneak in behind Danny without being noticed despite not actually being a student but this man always flinched when he spotted him and watched him warily. Phantom didn’t like Danny being so distracted from him, but this other mortal was pretty interesting. He seemed like he just couldn’t not notice Phantom.
“What are you thinking about?” Danny asked almost absently, icy blue gaze drifting to Phantom. Phantom’s gaze snapped to Danny, eager for his attention.
“I wasn’t thinking anything.” Phantom told him, definitely lying.
“Is it that guy again? Duke Thomas?” Danny sighed and shook his head with a rueful smile.
“Is that his name? Interesting…” Phantom hummed thoughtfully, floating closer to Danny.
“He’s probably sensitive, don’t bully him for it.” Danny scolded gently.
“He can definitely see me.” Phantom observed his eyes glued to Danny’s, Danny’s expression turned to surprise. Phantom loved how expressive Danny was.
“Oh, that’s pretty unusual. Do you think he’s a medium or something else?” Danny couldn’t help but wonder before shaking his head. “It doesn’t matter, we need to leave the poor guy alone. He looks so spooked!”
“One might say he seems haunted.” Phantom joked, nuzzling his face into Danny’s neck and causing him to stifle a giggle.
“Stop it, I need to focus.” Danny protested half-heartedly.
“Okay, okay. I’ll be good. But you have to become one with me later.” Phantom requested kissing Danny’s chin.
“Okay, once I finish this we should have time…” Danny agreed, his cheeks flushing pink and a giddy sort of smile on his face.
“Mmm, I look forward to entangling with you.” Phantom spoke softly into Danny’s ear causing him to flush even darker.
“D-don’t make it sound weird.” Danny whispered.
“It’s not weird Starlight, we were meant for each other.” Phantom told him. “My perfect half, my guiding light…I’d still be lost to the void if not for you.”
