Hometown Romance introduces Si, a high-society heiress eager to lead her family's company. However, her parents, viewing her as spoiled and irresponsible, appoint her younger sister instead. When the family business faces a critical crisis concerning a vital land lease, negotiations with the powerful landowner, Klaokawi, abruptly fail. In an astonishing twist, Klaokawi offers a lifeline: she will renew the essential lease, but only if Si agrees to marry her. This unexpected proposal forces the two women, who hail from vastly different worlds and possess completely contrasting lifestyles, into a peculiar arrangement. As they navigate this strange new reality, their initially adversarial relationship transforms into something far more intricate and emotionally complex, challenging their preconceptions and leading to an unforeseen connection.
