Dousei Doumei

Yuki, a male student, is frequently taken advantage of by his seniors due to his passive and accommodating nature. In stark contrast, his female namesake possesses a volatile temperament and an impulsive tendency to resort to violence before seeking clarification. Despite sharing the same name, these two individuals embody diametrically opposed personalities, creating an immediate and inherent tension between them. Their lives become unexpectedly intertwined when their respective parents marry, suddenly transforming these contrasting strangers into step-siblings who must now navigate a shared domestic existence. This newfound familial bond forces both characters to confront their differences within the intimate confines of their new household. The pushover boy and the quick-tempered girl must learn to coexist despite their clashing dispositions, setting the stage for inevitable interpersonal friction and comedic misunderstandings. As they adjust to living under the same roof, the dynamic between the gentle Yuki and his aggressive stepsister evolves beyond mere coincidence of naming, challenging each to adapt to a relationship defined by both obligatory family ties and profound personality conflicts.
