She was jealous and possesive

Phoenix clenched her jaws. Inhaling, she parted her mouth and said, "Mr Qin, don't you own a shirt?" she asked with a huff, "you want to take me to tour around looking like that?" she glared at Ashton and left him standing there in bewilderment. 

Walking towards where Tiana was, Phoenix grumbled inaudibly. 

Tiana was by the pool watching Ethan, and the twins played inside the swimming pool. 

Phoenix's eyes were looking at Ethan. Unlike Ashton, Ethan was wearing a short-sleeved swimming T-shirt, with his shorts.

She looked back at Ashton and sent another sharp glare towards Ashton before she sat next to Tiana, "can't he wear a t-shirt while swimming like Brother Ethan?" murmured Phoenix.

Tiana heard Phoenix. She trained her eyes towards Ashton and covered her mouth to stifle a laugh. 

She then closed her eyes and turned her head towards Phoenix, "I didn't look," she teased Phoenix. 

Phoenix grumbled again.
