Kudo was pushed into the bathroom and the door was closed. The boy stared blankly at the frosted glass door, in which his face was reflected blurrily.

The person I just saw outside is...

There was a sharp pain in my head, and a pronoun that should have been familiar flashed in my mind unsteadily.

Who is it?

Still unable to remember, Kudo's azure eyes blurred as if he was looking at the reflection inside the glass door, yet it was as if he was remembering someone through that blurry figure.

Is it...Mom and Dad...?

Mom and Dad?

He repeated the two words in a daze. The strange tone came out of his mouth and remained strange when it dissipated into the air. There was no sense of familiarity at all - it was as if he had never uttered these two words before.

...No, not really...He used to seem...

My head suddenly hurt, and blurry images kept flashing in my mind, making it completely chaotic.

——

Dad will find me.

...Who is it?

Kudo stared at the trembling child who was hugging him in the corner with his eyes wide open in confusion. When he reached out to touch the child, the picture suddenly shattered and then froze in a farther place.

The child still hugged himself, buried his head in his knees, with only a lock of hair showing.

dad……

Kudo looked at the child and had an inexplicable feeling in his heart, familiarity mixed with strangeness, very confusing.

As if sensing something, the child raised his head and looked forward, revealing a pair of sapphire blue eyes washed by water, which clearly expressed fear.

"dad?"

But there was no one in front of me, only a ball of cold air.

Standing not far away, the black-haired boy who looked just like the child had some confusion in his sea-blue eyes. He slowly reached out his hand and touched his heart, the panic in his eyes almost unable to be concealed.

Is this him...? But why, why can't he understand why he is crying?

The brain seemed to be completely different from its previous self. The boy, who had lost the most important thing, could not understand his former self at all, and thus developed a deep panic.

If he cannot understand, then what is he now? Can he still be considered a "human"?

The child seemed to suddenly see him, stood up, and stumbled towards him, with his arms outstretched as if he was reaching for his own salvation.

But as he ran, the picture gradually broke apart, until the child ran to within two meters of Kudo. The picture completely broke apart, and the child turned into a tiny speck of dust and disappeared from this place.

The black-haired boy had reached out his hand to hold the child's hand at some point in time.

The past self runs towards the future self.

Everything is fine, but the gulf of time separates them. Kudo cannot change the past, not to mention that this is just his memory and he does not have the ability to change the past.

As the first memory emerged, it was like opening Pandora's box. A series of memories came one after another, and the chaotic fragments gathered together gave people a splitting headache.

I reached out and turned on the shower, and clear water poured down on my head. The water should have been very cold, but probably because I had been outside in the rain for too long, I didn't feel anything when it poured down on me.

On the contrary, when the cold water gradually became warmer due to the effect of the water heater and poured on his body, the boy shuddered violently.

He stepped back suddenly as if he was scalded, and only reacted after a few minutes, standing under the shower again.

Ten minutes later, he opened the door with steam in it, and at first glance he saw a banner that read "Happy Birthday" hanging opposite him.
