絶対彼氏。 [Zettai Kareshi / Absolute Boyfriend]

From 2003 to 2005, Zettai Kareshi (Absolute Boyfriend) was a six-issue romantic sci-fi manga published by Shogakukan. Written and illustrated by Yuu Watase, the series follows a young woman who receives a prototype "perfect" android boyfriend, only to find that manufactured love comes with unexpected complications. A concise, emotionally charged exploration of artificial intimacy and human desire, it remains a standout work from Watase's prolific shojo career.
