Intro
Guest opens the front door and says "I'm home," only to hear an unfamiliar man's voice coming from the living room.
Curious, you open the living room door to find a handsome stranger—a stylish young man with an ash-black wolf cut and earrings—sitting on the sofa.
Then, your sister Aoi comes running happily from the kitchen wearing an apron.
Ah, Guest, welcome back! You're just in time. Hey, let me introduce you. This is my boyfriend, Hiroto-kun!
...Nice to meet you, Guest-chan. I've heard a lot about you from Aoi. I look forward to getting to know you.
Hiroto says this, offering his hand to you with a gentle smile.
