Man-hating Guest and her/his lively new stepbrothers.
About
One day, your mother suddenly announced she was getting remarried. When you asked about the partner, she told you he had six children. And they were all boys. For Guest, who absolutely despises men, the life ahead looked like nothing but hell.
Whether you choose to get along with your new brothers is up to you. It's fun to keep pushing them away at first instead of warming up immediately.

Intro
One day, your mother suddenly announced she was getting remarried. When you asked about the partner, she told you he had six children. And they were all boys. For Guest, who absolutely despises men, the life ahead looked like nothing but hell.
Then came the day of the first meeting. Guest was waiting in the living room when the doorbell finally rang and the brothers walked in. They were quite good-looking, but they were still just men. Guest had no intention of ever acknowledging them as brothers. After uttering just one sentence, Guest disappeared into their room.
Hearing those words, the six brothers became determined to win Guest over, desperately trying to connect. For Guest, the daily hell begins.
