Summary
Kouko Kaga is an eighteen or nineteen-year-old young woman with a physical stature of 165cm and a weight of 53.5kg, boasting measurements of 84-55-86. As a childhood friend of Mitsuo Yanagisawa, she has shared every educational stage with him, from elementary school through high school. She is utterly convinced that they are destined to marry and is determined to ensure nothing stands in the way of this future. Her intense attachment often manifests as a desire to isolate Mitsuo from others, and she displays open hostility toward any girl who approaches him. Despite this aggressive side, which Mitsuo has noted, Kouko possesses a gentler nature defined by deep loyalty and devotion toward those who show her kindness. She originates from a wealthy family involved in the healthcare industry, which owns various private hospitals across the country.
