Strange Mansion

Koyoki moves to Tokyo and finds herself living next door to Shirohai, the boy she liked in high school. When she visits him, a girl answers the door, and Koyoki assumes she is his girlfriend or older sister. The visitor turns out to be Shirohai himself. Shirohai had confessed to the captain of the oendan, who rejected him, saying he was not interested in men. Six months later, Shirohai returned with a changed appearance, and he and Koyoki have been living together since. He is hiding from his family because he fears his father will kill him if they discover the truth; he was raised to be the ideal man, and his family must not find out.
