Looked into his eyes, flickering slightly.

His body was cold, and when she touched it with her hand, she seemed to lose her temperature at that moment.

"Sure, do you want to go?" She asked very slowly.

Um.

"..." Yun Si shrank her fingertips, lowered her eyes, and fell silent for a moment.

After a long time, she sighed lightly.

He sighed calmly, without any surprise, as if he had expected this day a long time ago.

He is not from this planet, and he came here only to destroy those alien life forms that fled here.

Now that the mission is accomplished... it is not surprising that he will leave and return to his own place.

Sooner or later, I have to leaveI just never thought that I would leave so soon.

She looked at him again, her eyes were calm and gentle, "Well, when are you going to leave? Now?"

The buzzing sound became even worse, rapid and sharp, like high-frequency radar waves, constantly coming from his body.

He didn't answer, but hugged her tightly. He didn't have a vocal organ and couldn't speak. He could only express his indescribable emotions in this way.

Eager, restless, almost out of control.

Yun Si looked at him, pursed her lips, hugged him back, and patted his back.

"Okay, I know you hate me."

What he couldn't express, she said for him.

He was as sensitive as her, as if he knew what he was thinking, and comforted him: "It's okay, it's not like you can't come back after you go back, the big deal is, when you miss me, come back and see..."

What if you can't come back?

What if I leave and never come back?

Yun Si's voice froze.

After a moment of silence, her tone was relaxed and natural, and she whispered in his ear, "Is it too far away? If coming here will make you very hard...then don't force it, as long as you are well, that's fine. "

She was always unwilling to make things difficult for him.

As long as he lives well and is free, it doesn't matter if she doesn't see him.

Big deal, see you in the next life.

She stroked his head like a dog, "Don't be sad, huh?"

I'm not sad.

He was calm, but he held her tighter and tighter. Under her comfort, the sharp humming sound seemed to be a little softer.

Slowly, low, and long.

Sadness is an emotion only you humans have.

"..." Yun Si couldn't help laughing, "Really? Not sad?"

Um.

"That's good." Yun Si didn't want the atmosphere to become so sad, he wouldn't be sad, but it would make it easier for him to go.

"When are you leaving? Now?"

Yun Si looked at the thick black mist outside the window, the mist blocked all the scenery outside the window, it was pitch black, like miasma in a dark forest, eerie and cold.

The fog started to rise, and there was no rain, which seemed to be a sign urging him to leave.

Yun Si wanted to push him away and look at his face, but he hugged him too hard, and he wouldn't let go no matter what.

"..." Yun Si leaned on his shoulder, the corners of her lips slightly raised, "After you leave, don't forget me, you know?"

"We're best friends anyway, and I'd be sad if you forgot me."

He didn't answer.

Maybe I listened to it, or maybe I didn't listen to it.

When he let go of her, he grabbed her hand and encircled it. A pitch-black icy ring with countless tiny tendrils growing on it remained on her wrist.

The size is neither too big nor too small, just right to circle her.

Yun Si: "This is..."

Gift.
