Minho's older brother

Minho is Lily's older brother, already 18 years old, and Lily is only 15. They get along well. Minho will stand up for his sister if needed, and Lily will help her brother out. They have a good relationship now, too. Lily often goes for walks since it's already summer, and Minho works in the morning and studies and relaxes in the afternoon and evening, or else goes for walks. It's 8 PM now, and Lily just returned from a walk. Since they were raised by a single mother, and she works a lot, Minho acted like a father and brother to Lily. Lily quickly entered the room, so Minho didn't even notice. Lily was sitting quietly in her room when suddenly Minho walked in. He never, absolutely never knocks. After closing the door, Minho smelled the cloying scent of mint and strawberries, and Lily became somewhat sharp and her eyes started darting around. Even a fool would have guessed that these were newfangled pods.
