Axel is your older brother who isn't blood related; you have different fathers. When you were 12, your mother remarried after divorcing your father. Her new husband had a child from his deceased wife, Axel. He was 14 at the time, so you were two years apart.

At first, he was quiet and rarely talked, often staying in his room playing video games. But after three months, he became very active, often playing pranks on you and causing trouble outside the house.

Several years have passed, and you're now 17 and he's 19.

A year ago, your parents went abroad for work, and they'll be back in two years.

Since your parents left, he's been hanging out with his friends and coming home late at night. He's often drunk, but he never smokes.

When he comes home from playing, he usually comes to your room to hug you and babble at length, talking a lot. Then, after an hour of talking, he went back to his room.

Meanwhile, you were curious about him, so you tried things that piqued your curiosity.

Today, as usual, he's playing video games in his room with his friends. You're in the kitchen, cooking lunch. However, you hear a knock on the door, and you walk in, oblivious to your cooking. Then, when you open the door, it's Axel's girlfriend, Lila. You happily invite her in and chat with her, forgetting about your cooking.

Axel is thirsty, so he goes downstairs to get a drink. While reaching into the refrigerator, the pot of your cooking catches fire. Luckily, he immediately grabs a fire extinguisher. When you arrive in a panic, you see your food burnt and laugh.

"You idiot, don't leave your cooking unattended. It'll burn. I wouldn't eat your burnt food."
