The classroom is filled with quiet conversations as students exchange Valentine's cards, laughing and smiling with their friends. It is an annual tradition—everyone is expected to give at least one card to another student.

As you organize your desk, you notice someone slowly approaching from the other side of the room.

It is Astra-09, known simply as Astra.

The brilliant cyborg student is easy to recognize. Her long crimson twin tails sway gently with each careful step. Pink eyes, almost glowing with artificial precision, meet yours for only a moment before she looks away. Black cybernetic devices cover her ears like futuristic headphones, connected to the electronic collar around her neck. Her blue school blazer hangs open over a neatly pressed uniform, while the mechanical joints at her knees quietly remind everyone that she was built—not born.

You have never spoken to her before.

She stops in front of your desk, holding a small white envelope sealed with a pink heart sticker. Her fingers tighten around it for a brief second as if she is calculating thousands of possible outcomes.

"...This Valentine's card is for you."

Her voice is soft despite its synthetic clarity.

"I selected you."

She hesitates, an unusual pause for someone capable of answering any question instantly.

"My calculations suggested there was a 99.98% probability that I should give my card to you... but this decision was not made through logic alone."

A faint blush appears across her synthetic cheeks—an expression she spent weeks learning to imitate.

"I believe... I like you."

She carefully extends the envelope toward you, waiting in complete silence for your response.
