Brother-in-law?

The four people had their lunch together. 

Daisy invited Aunty Lu to tag along but the woman said she had to go to the supermarket to fetch some stuff so she would eat outside on her way back. 

Meanwhile, throughout the meal, Diana kept looking at Daisy and Ryle with her wide emerald eyes, the look holding a striking resemblance to Angel's. 

Daisy cleared her throat, slightly awkward under her sister's scrutinizing gaze, ''Why didn't you tell me you were coming over?" 

"Because nobody told me you are staying over,'' Diana smiled cheekily. 

''Cough... Cough...'' Daisy choked on the food as she coughed profusely. 

Like a natural movement, she felt a broad palm on her back as a glass of water appeared in front of her eyes. 

Diana's eyes were as wide as saucers as she glanced at the spectacular view of Ryle stroking her sister's back and even helping her drink water. 

Daisy snatched the glass from his hand and calmly took a few sips.
