Zhao Sinin had indeed heard of Mu Hanyan's great reputation but had no idea what he looked like. He only saw that Fourth Miss Zhao's attitude towards Mu Hanyan was very strange; as soon as she saw him, she couldn't take her eyes off him, now gritting her teeth and then furrowing her brows in thought.
