Like the children of other prominent families, Sia Cha (Alpha), the second daughter of the SW group, became engaged in an arranged marriage at an early age. In order to increase their genetic compatibility and get used to her pheromones, she was placed with her fiancée and his family since childhood. But her fiancee found his true love and asked her for a breakup. After that rejection, she suffered from omega pheromone intolerance for the next several years. That day too, she tried to get away from a party and take her rest, when a stranger approached her... "I want a child with you, no strings attached. Just give me one night!" For the first time since her breakup, an Omega appeared whose scent did not trigger her disgust. (Source: Bomtoon, translated)
