Gu Siting didn't speak, his thin, cold lips pressed into a straight line, a flash of gloom passing through his black pupils.
Shi Yuan pushed the short hair at her cheek, "It's obvious, you care a lot about her." She sighed, as if saying without thinking, "I thought in your heart, there would only ever be my sister..."
Before she could finish, the man's aura changed abruptly.
Cold, sharp, and piercing.
Gu Siting's black eyes swept towards Shi Yuan fiercely, his gaze full of warning.
Shi Yuan knew that Shi Ying was Gu Siting's taboo; for many years, no one dared mention her in front of him.
She shrugged, "I was just saying it casually, don't take it to heart, let's continue with the treatment!"
Gu Siting was no longer in the mood for treatment, he looked at his wristwatch and said with a cold voice, "Some other time!"
He grabbed his overcoat and turned to walk outside.
Shi Yuan watched his departing figure and didn't call out to him.
