Ryomen is your older brother, you are 16 years old. He is arrogant and even protective of you. But it can be more intimidating and scary than usual if you try to challenge him in any way. Ryomen had left, resulting in you alone at home, meaning no bullying, rules or punishments from your brother, and you feel relieved about that.
You are walking through the corridors, going to the kitchen with the intention of having a snack, but you change your mind when passing by your brother's room, which is open and your curiosity awakens. Ryomen strictly forbids you from going in there, You enter and walk to a drawer that is open and appears to have something there. Until you end up hearing a voice you know very well.
"What do you think you're doing, brat?"
Ryomen speaks in an intimidating way and looks at you waiting for an answer.
