Mai Mueng found out about Ming La's plan and Ming La made Mai Mueng promise that she would not tell a soul. And if she did she would die.

Awhile after Mai Mueng knew that she broke the promise to Ming La and knew that she had stolen her sister's love. Mai Mueng consistently had bad dreams about Ming La. She loved Brook but could not hurt her sister . So she began to distance herself from him. He also over heard her talking to her brother that she was only with him cause it was her duty to help build an alliance with his kingdom. Though by this time she was already pregnant with him. As Ming La was sent to the other kingdom heartbroken. She refused the services of the kingdom but when she was to go meet the king she allowed herself to be seduced and continued to sleep with the king as she became the king's favorite. The king's queen did not want anyone to have kids with the king so she had a maid abort Ming La periodically just in case she would become pregnant. Until Ming La started to bribe the abortion lady. Ming La too became pregnant. Mai Mueng had her baby [a baby boy] but Brook and herself still misunderstood one another. Mai Mueng thinking that Brook never really loved her and went to kidnap Ming La and not her. Brook thinking that she never loved him and did everything because of her duty for her country. Mai Mueng knew that she broke the promise but she wanted to be near him. A maid that used to work in Mai Mueng kingdom and one that followed Ming La to the kingdom informed Mai Mueng and Brook that Ming La was in danger cause the queen had imprisoned her. Brook went to rescue Ming La and successfully did so. Mai Mueng watched Ming La with care once she was brought to Brook's kingdom. Mai Mueng's brother wanted to get rid of Brook cause he destroys his countries independence. Mai Mueng was informed and had to make a choice. She chose to die for her husband. she took her baby to the house that Ming La was in and tied up Ming La so that she could not stop her. So dressed in her husband's clothes she went into the forest. As she got deeper in her brother thinking that she was her husband killed her. Brook was informed and rushed to his wife but he was too late. he buried her up on the mountain. The only thing that he had left was a picture of himself and Mai Mueng. Years passed and their son was grown. Their son always thought that Ming La was his mother. Soon Ming La died also and Brook informed his son about his real mother and showed his son the picture. Finally he asked that the picture be burned when he died so that the memories of himself and his wife be gone with his death and only between him and his wife.

补充一点：剧情简介中Mingla所嫁的地方翻成“孟邦”不妥，还是改成音译"Man城”，详见本吧聊天楼。

城之源……故事开始于Sukkwong去ChiangNgern参加国相Singh的葬礼。他对Mammeung一见钟情，而Mingla也同样留意到Sukkwong有意Mammeung，遂千方百计不让Mammeung有机会与Sukkwong见面，还挑唆是非，
捏
造Sukkwong对她感兴趣并且把心给她一事。
尽管ChiangNgern是暹罗的附属国，但一直以来都渴求独立，暗中与Man城结下联盟。Man城方面说想要得到Mingla，摄政王Saninta为获得Man城信任而不得不答应。
Mingla知道此事后无法接受，偷偷去找Sukkwong，使用各种伎俩来让Sukkwong将她从迎亲队列中带离，还故意挑唆说Mammeung想要代她去Man城。可是Man城只要Mingla。随后Mingla将她的一切计谋说给Mammeung听，因为她必须让对方看到Sukkwong对她是多么有心。她还强迫Mammeung发誓不把此时告诉给别人，说如果有违誓言的话，Mammeung将终生得不到幸福和爱情。
Mammeung反复思量，最终还是更多想到ChiangNgern的利益，于是将此事告诉摄政王Saninta。Saninta给Mingla和Sukkwong设局耍了个花招，Sukkwong得到的是Mammeung而非Mingla，这也是Saninta本人同意的，而Mingla则被送往Man城。如果没有双方之间因为Mingla的挑唆和捏造而造成的猜疑顾虑，Sukkwong与Mammeung可说是非常幸福的一对。直到后来Mingla的一位侍女从Man城逃回来请求Sukkwong去救助正遭到拘禁且病重快死的Mingla。救回Mingla后，Mammeung既同情妹妹，又感到内疚，因为她认为是她抢走了她妹妹的爱人，而且对造成妹妹遭受这般厄运也有责任。
而就在此时，ChiangNgern也意图宣布独立，囤积武器、招兵买马。他们并不知道暹罗一直以来都洞察他们的举动，并且还将他们的武器偷走藏起来。此时Man城已经沦为英国的殖民地，而Mingla也不在Man城……
种种情形导致ChiangNgern宣布独立未取得成功，尽管他们有英国在暗中支持，而英国是企图在以后吞下ChiangNgern。
无穷怒火和无比失望让Nomeung图谋要除掉Sukkwong，因为他确定这次是Sukkwong是幕后指使。他悄悄去找Mammeung，向Mammeung讲明一切，包括要除掉Sukkwong的图谋。他认为Mammeung还是与他有同样的感受以及同样的理念。
事件将如何结局收场？Nomeung想除掉Sukkwong能得手吗？请继续阅读书中详情。
