Both Thai LGB stories feature a significant focus on marriage, what it means to be married, and marriage equality. Both stories start off with an arranged engagement (though GAP involved an arranged engagement with an outside party, rather than between the leads). Both couples have trouble communicating their wishes to each other. Sam and Kuea are both wealthy heirs, with Mon and Lian working their way up the chain in order to be able to stand by their love interests' sides.
Both romances center around a boss and employee learning about each other, realizing their misconceptions about each other, and falling in love. One of the main leads also faces a lot of family pressure and past trauma that makes them repress their own wants and needs, but is able to overcome it thanks to the support from the love interest and friends. Furthermore, they both feature strained sibling relationships and manipulative antagonists.
