Let me list some characters' names here so hopefully no one will get confused.
Neung/Anawat - James J, a man who never lose in anything
Poom/Huthairut - Yaya, an orphan who was raised by her aunt (her mom' sister) and her husband
Pook - Yaya's male cousin, one of Neung's best friend
Paan - Yaya's female cousin
Pinit - a sick man, one of Neung's best friend, in love with Poom
Punny - Pinit's younger sister, one of Poom's best friend, in love with Pook
Song - Noey, Pook's and Paan's cousin from the dad side
Pinit's mother doesn't want her children to get involved with Poom because she considers herself blue blood (come from a good and hi-so family) On the other hand, Poom is an orphan and came from a not so rich family; her aunt happened to marry into a good and rich family. She wanted her daughter Punny to get together with Neung. The two siblings often times lying to their mother that they went to see doctor or Neung just for cover up, but in reality they went to see Poom and Pook respectively.
Song and her mother told Neung's dad that Poom pretended to drown so Neung could save her. They said Poom is a type of person who always wants to draw attention to herself, wants to use her look to catch men and to toy with their hearts.
Song's mom said Poom's physical appearance is not that pretty but why so many men fall for her. Song then lied to her mom and said that she has so many suitors, a lot more than Poom. Her mom asked what their names and how come she has never met them. Song said there were so many men that she couldn't remember, so the next time she meets them again she will introduce them to her mom, lol.
