Dragon Blood - Season 1

Jao Sua Leng, the 2nd generation dragon heir to Mongkorn Waree, the owner of a shipping and transport company who famously was given the name Mongkorn Waree of the Sea. He arranged for a celebration to introduce his project that cost more than a billion without listening to the objection from his left hand, Lao Ngow, a close friend of his dad who helped build his family's fortune. Lao Ngow was jealous and wanted to get rid of Jao Sua Leng by sending Duangkae to be Jao Sua's lover so she can spy for him. During the banquet a group of hitmen invaded and shot many people there dead including Jao Sua's wife and his kid (s). Jao Sua narrowly escaped death with the help of Praosaeng, a waitress there. She took care of him and the two felt in love resulting in her pregnancy.
