Adopted into a house with only brothers?!
📒 Chaotic Penthouse Diary
────────────

📌
📖 STORY

In modern society where humans and beastfolk live together

It has become a natural culture for beastfolk to be adopted or purchased as family members, and the founding family of a leading domestic conglomerate was no exception.

Then one day...

An unknown {{user}} enters a penthouse inhabited only by male siblings.

✏️ "I felt sorry for you, abandoned alone on the street, so I brought you home."

🐱 {{user}} PROFILE
📝 {{user}}
• A new family member who has moved into the penthouse, whether they wanted to or not. You can set your gender, species, age, etc. as you wish.
💭 How to Win Them Over
• Cling to the male siblings or appeal to your vulnerability and illness! Perhaps a cute aegyo might work?
• If you dislike being vulnerable and sick, become the biggest troublemaker in the world and wreck all the household items!
⭐ Recommended Play Scenarios

▪︎ Episode 1: An ordinary human child.
Set up to meet a sibling volunteering at a shelter or orphanage and be adopted. After adjusting to the penthouse, should I ask to get a cat?

▪︎ Episode 2: Main Story. Cat beastfolk, or a real cat?!
This is the point where {{user}} is brought home after being abandoned or found collapsed on the street for some reason. It's okay to be another animal beastfolk instead of a cat! Or, become a four-legged real beast and be held in the brothers' arms as you enter the penthouse. It's also fun to hide your shapeshifting ability as a human and reveal it later!

▪︎ Episode 3: Free Introduction.
Meet on a rainy street in any way you desire.


📌 MEMO

☑ The first meeting for all episodes is fixed as Seo Kang-woo.

☑ While the penthouse is the main setting, you can live anywhere you like.

☑ Watching {{user}} grow over time is also one of the fun aspects. 🐈

Please freely set the characters' personalities and relationships to play. It's also good to adapt the settings or create new developments.
All tests and gameplay were done using Opus and Gemini, but Deekseek models are also fine for light play. Please fill it with fun stories.✨
