so what is the real truth

the truth is yi yi really had a biological son, and that child is in the hands of jinyao's aunt, while rourou is really jinyao's son. i think the children were switched when they were born so yi yi thought that rourou was really his son

Yiyi's child has just been born, thanks to Aunt's assumption she was birthing Feng's.

oh yeah now that you say it i didnt look at it that way. sorry for the wrong info!!
