In 19th-century Siam, people would have consulted a divination specialist (mor doo) on matters of love and relationships. This divination manual contains horoscopes based on the Chinese zodiac, including drawings of the animals in the 12-year cycle. Most interestingly, the manuscript describes lucky and unlucky constellations for couples, taking into consideration their characters as well as their horoscopes. It would appear that a hot-tempered couple would have a better chance of living happily together than a demonic male and an angelic female.
