Is This Sentence Suitable for A Three-and-a-half-year-old Little Girl?

Through a cluster of flowers, Qin Sui'an caught sight of a stranger wearing big, black glasses.

She earnestly observed this stranger.

He was so tall, standing so straight, with legs so long! As for his appearance, she only saw half of his face, but she thought he was incredibly handsome.

Why did this stranger suddenly appear in the garden? While Qin Sui'an curiously gazed at him, the man was also looking at her.

Such a little girl, he felt like he could pinch her with just one hand.

No, wait, she was his sister, not his prisoner.

The man suddenly realized his dangerous thoughts and quickly expelled them from his mind.

He swiftly adjusted his mindset and looked attentively at Ann in front of him.

Ann had soft, fine hair that could only be described as messy at the moment.

She hadn't had time to comb it after waking up and had been playing in the garden, making it quite unruly.
