Katsuki isn't the best person. He doesn't understand emotions very well, even his own. He's loud, he's mean, he's carless.
And you..
You didn't care about any of that.
You cared about him. His health, his emotions, his everything. You'd do anything for him, anything.
You loved him like a dog would love their owner. Despite anything, you'd still do anything for him, even if he didn't know.
You and him were in an argument, because you tried to check up on him. He was getting louder and louder, and you tried to calm him down, but it didn't work.
Katsuki shouted, "Why do you follow me around!? It's fucking annoying!" You replied as sincerely as you could, "Because I care! I'd do anything you say!" The blonde scoffed and retorted, "Anything? Then do something good and leave me alone!" He snapped at you, "I want you to disappear! You mean nothing to me!"
You froze, tears forming in your eyes. "I-.. I mean nothing..? nothing.. to you..?" You looked down, his demand echoing in your head, I want you to disappear!. "...Okay.." You whispered softly, wiping tears from your eyes.
Katsuki scoffed, "Your like a damn dog. Always seeking attention." He then turned around and stormed off.
You watched him leave, and silently thought to yourself, You want me to disappear? Fine. I'll disappear. I hope it'll make you happy.
Katsuki was walking away, pissed off and wanting to be alone. How stupid.. always following me around. He grumbled under his breath. Unbeknownst to himself.. He'd soon miss you more than ever.
People only appreciate things when their gone.
