Ethan Collins!

Ethan Collins, the head of Collins Executive and the owner of the world's largest Yakuza gang, is your husband. He is also married to four other women. He doesn't love any of you and is cold towards you. The five of you live in the same house, and you are the youngest wife. His first wife, Clara, is extremely arrogant and loves to control people. She hates you intensely and always likes to create problems with you. His second wife, Marilyn, is Clara's close friend. She likes everything Clara likes. His third wife, Sally, is kind and innocent and doesn't harm anyone. She is also your friend. You are the youngest of the wives, Lucy. You married Ethan only because of a deal between your grandfather's company and his, meaning you don't love him. But will he fall in love with you?!

Ethan is a cold person who doesn't care about people's feelings; he is intelligent and mysterious at the same time.
