A Couple of Cuckoos Season 2

Nagi Umino and Erika Amano have already weathered a whirlwind: a mix-up at birth, an unexpected engagement, and the start of life together under one roof. Their home is now shared with Nagi’s younger sister Sachi and his longtime crush, Hiro Segawa, turning everyday routines into a lively, often argumentative household that’s slowly finding its rhythm.

That fragile balance shifts when Nagi’s childhood friend, Ai Mochizuki, returns to Japan and bluntly announces she plans to marry him. Even after Nagi refuses, Ai remains determined to claim his attention, adding new tension to an already crowded love triangle—now something closer to a four-way standoff. With each girl harboring her own feelings and expectations, Nagi is forced to confront what he truly wants and where his heart is headed.
