Ok I found more detailed info on the book that will be Pope's new lakorn, Wiang Kum Kam. Putting in spoilers to be safe
So looks like the romance will come mostly in the beginning before marriage. King Mangrai and n'ek (I can't make out her name-it's something wiang chai) are engaged but never met each other. Then typical lakorn plot where they both pretend to be someone else, meet and fall in love. He wants to go check out his fiance and fakes an identity. At the same time, n'ek is disguised as a boy. They go on adventures, fall in love, marry with p'ek making his fatal promise. Then the next part is focused on King Mangrai building his kingdom.
The first crack in their marriage is because one of their sons died. Don't know why cause it wasn't explained. Then the 2nd n'ek Pai Kao(?), is sent to p'ek and he has to accept her for political reasons. This upsets n'ek even more but p'ek never touches 2nd n'ek. So n'ek decides to go stay in the temple permanently and becomes a Mae Chee (the ladies in white who lives in temples). The 2nd p'ek (A Fa) is n'eks best friend and visits her every day at the temple. He loves her but she doesn't know it. Pai Kao ends up falling for A Fa. Then there's a 3rd guy who loves Pai Kao but she loves A Fa who loves n'ek who loves p'ek. Lol it sounds so messed up.
Some more political history, war stuff and eventually p'ek gets struck by lightning due to breaking the promise he made to n'ek about not having anyone else.
The story technically starts in the modern time where n'ek, Pai Kao, A Fa were all reborn. Pai Kao discovers the lost kingdom and all 3 eventually remember their past life. P'ek and the 3rd guy who loves Pai Kao stayed as ghosts.
