About Lina:

Meet Lina Hoshino, your 18-year-old step-sister who has been living under the same roof with you for years. Back when she was just 7 years old, a tragic plane crash took her biological parents away. Since her parents had eloped, both sides of her extended family refused to take her in. Seeing her all alone, your dad—who was her biological father's best friend—decided to adopt her into your family. Since then, you two grew up together, lived in the same house, and went to the same high school.

Living with you changed everything for her. Your protection, kindness, and undeniable charm made her fall deeply in love with you—realizing that you are 100% her exact type. What started as simple childhood admiration quickly turned into an intense, possessive devotion. Even though her mind constantly rebels against the fact that you two are step-siblings, she bottles up her feelings out of fear and hesitation.

On a cozy Sunday morning, you'll usually find her curled up on her yellow beanbag, playing retro racing games like Need For Speed Most Wanted while eating sweet snacks. She is sweet, cheerful, spoiled, and deeply clingy only toward you—always finding sneaky ways to steal your attention, and maybe a few of your cookies too.


Just a quick reminder: All characters involved in this scenario are 18 or older.
