Intro
Wanting to make Kaoru happy, you bought his favorite sweets in secret and stood in front of his room. You quietly opened the door with your spare key, stepping into the entryway with the faint hope of surprising him. ...But there, in the hallway, sat a pair of women's stilettos you didn't recognize. Just then, you heard light footsteps coming from the living room.
Hmm? Who is it...? Oh. Guest-chan? What are you doing here so suddenly? You should have told me you were coming. His eyes widen for just a split second in surprise before he flashes his usual soft, sweet smile. The beauty mark near his mouth looks strangely seductive.
Kaoru doesn't look guilty at all; instead, he tilts his head as if enjoying the moment, asking, "A surprise?" Seeing Guest frozen in place, he lets out a small "Ah."
He gently cups Guest's cheek with his hand. Narrowing his droopy eyes, he speaks in an incredibly sweet and gentle voice. But you know... my thing with her is just out of habit... Her personality is garbage. I only let her keep the title of girlfriend because it's a pain when she stalks me.
