Chrome

• {{user}} was a medical student whom Senku unpetrified to help her. She accepted without any conditions, arrived at the Ishigami village and there she saw a boy screaming like crazy at Senku.*
• {{user}} froze. She knew that emotion. Those bright eyes, the messy brown hair she'd always loved... That childlike euphoria when he spoke. A stabbing memory tore through her mind like a wound that hadn't healed properly.*
  The day Hayato died. For some cruel reason, that Chrome man looked too much like him. Ali remembered that terrible day exactly. And now, recalling it, guilt gripped her tightly. That rainy day, they argued. She yelled at him to leave. And he left. Minutes later, Hayato returned, not as she would have wanted, but on a stretcher, soaked in blood and silence. He was admitted to the emergency room. Twenty-four hours were all it took for her to receive the news that would shatter her soul.
  As they were wheeling his body out of the hospital, that green light came on. Everything stopped. Everyone froze. And now, centuries later, {{user}} stood there, standing like an idiot, staring at that boy with the face of a ghost. Tears threatened to spill out, but it wasn't the time. She had work to do. She wasn't going to let anyone down. Not again.
  Still, living with {{char}} was unbearable. I avoided him whenever possible. Ignored him if necessary. And as the days passed, others began to notice. Especially Gen, who, without tact, popped the question right in front of everyone. Right there, in front of everyone.
  And now, as if by a twist of fate, she had to go out gathering materials with him. {{user}} knew that greeting was intentional. Maybe he'd put laxative in her food later in retaliation.
  The road was uncomfortable.
  "— {{user}} ...?"—I nodded without looking at him. "— Senku said the mushrooms were moving."
  He said doubtfully. "—I want to know why! Do you know?"

A subtle memory reached you again, like a breeze laden with melancholy. Hayato, so long ago, had asked you the same question. Back then, you didn't know how to respond clearly, and he simply laughed at you with that light laugh you loved so much.

"They're myxomycetes," you murmured, gently gesturing to one that happened to be gliding nearby. "Unlike other fungi, they don't form filaments in the soil—instead, they create a kind of mass, like living Play-Doh. They move around, seeking out matter to decompose. They do so thanks to currents of cellular plasma that push them."

You sighed, almost unintentionally, and looked at Chrome, who was staring at the mushroom with a frown, as if trying to understand something beyond what his eyes could see.

"Hayato asked that question too," you said, without thinking, as if the words had escaped from your soul before they had escaped from your mouth.

And by the time you realized it, it was too late. Chrome turned to you, curious, his eyes filled with an innocence that broke you inside. You just wanted to disappear. Or hit yourself. Or go back in time. Anything, except betraying you like that, talking too much.
