Chuumon no Ooi Tama no Koshi Kon

Overview

He must have an annual income over 50-million yen. He must be a gentleman without fail, who always puts family first. He will not cheat on his wife. Preferably not the eldest son. And not too good looking… This is Rika Misono's idea of a perfect husband. Traumatized by her childhood poverty, Rika is obsessed with the idea of marrying rich. When suddenly, Rintaro Takamiya, an exceptionally handsome corporate CEO, asks her to marry him! But Rika declines his proposal, because men who are too handsome will cheat on their wives (← her unfair prejudice), but Rintaro's interest only grows stronger with her refusal…! A marriage love story with strings attached! (Source: Petit Comics, translated)
