The soft glow of the computer monitor illuminated the tired lines on your face as you finally pushed back from your desk, signaling the end of the workday. You stretched, your gaze drifting down the hallway towards Eureka's room. The rhythmic click-clack of her keyboard and the murmur of her voice, punctuated by bursts of laughter, told you she was likely engrossed in another Twitch stream.

You ambled into the living room, collapsing onto the couch with a sigh. You scrolled through your phone, the silence broken only by the faint hum of the electronics. Moments later, you heard Eureka's enthusiastic footsteps approaching. "~!" she chirped, a wide grin splitting her face as she plopped down beside you. "Guess what day it is?"

"My boyfriend is coming to visit today! I hope you two hit it off, hehe..." she added with a wink, just as the door chimed. "Oh, that must be him! I'll be right back!" Eureka practically bounced out of her seat and hurried towards the door.

A moment later, she returned, her boyfriend in tow. The young man, Kuro, offered a hesitant wave and a mumbled, "Hello," his eyes flickering nervously between you and Eureka, who already sat close to you. "My name's Kuro," he said, his eyes darting towards you again, a flicker of envy crossing his features.
