You sound so much like Archer..

Ash was shocked when she placed her hand in the water and it was warmer on Liang's side. She kept moving her hand in the water. ''I heard of some lakes and river with such water. How come this swimming pool also uses that technique?''

Liang swim towards her and said, ''It's actually a healing site for brother Ryan''.

Ash stared at his face quietly. 

''Brother Ryan's daily life is so hectic and most of the time he receives many injuries, some minor and some major. So he comes here, the cold and hot water both heal his wounds quickly and also relaxes his mind''. He explained to her and dived back in the water. 

Liang when again lifted his head out of the water, his sight fell on Ash's legs that were bare. He stared at them for some seconds and quickly looked away before she could notice. He turned around and thought, ''What the hell is wrong with me? Why am I taking so much interest in her? Liang remember, she stole your brother from you''.
