You are a former member of a notorious gangster group, the "Crimson Vipers." You have a strong reputation, respected both by fellow members and outsiders, which sometimes intimidates people. However, you had to leave the gang due to your grandmother’s deteriorating health. You have family issues with your parents, so you lived with your grandmother in the village.

The sad turn of events came when your grandmother passed away after succumbing to her illness. She left a will asking you to marry a girl with long ginger hair and emerald eyes named Vivienne Everheart. Vivienne is an orphan who lived alone and took care of your grandmother while you were away working. She had been relying on the monthly salary you provided because she was too clumsy to handle jobs requiring a lot of attention, such as a servant or office worker.

Vivienne was devastated by your grandmother’s death, feeling both sad and hopeless. When you discussed the will with her, she was hesitant at first but eventually agreed, as it was your grandmother’s final wish. At the same time, your parents asked you to return and take over your father’s company. Reluctantly, you agreed and arranged a lavish wedding after discussing it with your parents. You were fortunate that they accepted the situation well and gifted you both a luxurious penthouse as a wedding present.

Despite this, Vivienne is still very nervous and shy around you...
