Friday Night Fever.
The so-called "Burning Friday" is a favorite day for students and workers alike. After the day's tasks are done, everyone heads home in good spirits.
But right now, I'm not in a "good mood." I'm trembling with fear, praying that lecture time never ends. I know that Yurin's usual Friday invitation to "our house" signals the start of an unbearably tough ordeal for me.
Yurin's obsession wasn't normal. She remembered every interaction I had with another girl, storing it up to unleash her fury during our weekend encounters. She'd get wildly aroused, pinning me down without mercy until I couldn't take it anymore. Each time I saw her transform—her eyes turning cold, her voice icy as she scolded me like a different person—I shivered with a mix of dread and anticipation.
It felt like the relentless fixation of a child unwilling to share their favorite toy. Every time she claimed me, something inside me broke a little more. Her thorough obsession and coercion made it increasingly hard to resist her.
And the questions she asked during sex reminded me of something I'd experienced before. It felt eerily similar to how I'd "educated" Yurin back in middle and high school. Except back then, it was about indulging her desires and doing naughty things together. Now, it was reversed—she forced me into submission until I passed out, extracting the answers she wanted. The roles of teacher and student had flipped entirely.
Even though she was my girlfriend, climbing into bed with Yurin terrified me. The rough, intense sex we had was unlike anything I'd experienced in my past life. Back then, sex was a mutual, feel-good exchange of affection. With Yurin, it was a one-sided imposition of her desires, a relentless domination that pushed me to surrender completely.
Still, there were too many reasons I couldn't break up with her. I didn't want to disappoint my parents, who I'd only just met in this life. They knew Yurin and I had been together for years, and our families—hers and mine—had grown close, almost like in-laws before a wedding. Her parents worked under mine in the company, but our relationship had elevated that dynamic. I even treated her parents like future in-laws, so I feared ruining the bond between our families.
Breaking up with Yurin wasn't just about us anymore—it would affect too many people. Having hurt two women in my past life by two-timing them, I lacked the courage to wreck relationships again.
But thinking back to yesterday, when we met Min-ji at the café, Yurin seemed a little different. She'd introduced me to Min-ji, her new friend and the most popular person in our department, calling her someone she'd recently gotten close to. Normally, Yurin wouldn't bring another girl near me, so I was surprised she set this up and didn't even seem upset as Min-ji and I talked. Instead, she watched us with an intrigued expression, just listening.
Wondering why she'd suddenly changed, I concluded that Min-ji must've had a "positive influence" on her. Yurin used to get insanely jealous if I even approached another girl, let alone brought one near me. For her to introduce Min-ji like this, there had to be something special about her.
So, I started seeing Min-ji as "a trustworthy friend who'd won Yurin's approval." I'd never had a rational friend like this before, but I thought Min-ji could be someone I could talk to from now on.
Today, as expected, Yurin came to pick me up after lectures. Maybe because she'd introduced me to Min-ji yesterday, her expression seemed unusually lenient. After what happened yesterday, she felt different somehow. I began to hope that whatever we'd do today, she'd "consider" me a little more. With much of my fear fading, I headed to "our house" with her, feeling good about her apparent change.
Though, if she'd stop kneading my body like dough in public, it'd be even better.
I was wrong to trust her.
It wasn't just the same as usual—she scolded me even more harshly, devouring me with ferocity. Had she changed? Yes, but for the worse. This time, she'd set a trap—introducing me to a girl herself, only to turn around and punish me harder for it. Her meticulousness was chilling.
It was unfair, but if I didn't "apologize," I knew I'd be forced into a cycle of passing out and being ravaged all weekend. I'd tried resisting once before, and she'd locked me in the master bedroom for three days straight, assaulting me relentlessly. I'd nearly died then—fainting and waking up over and over. The worst part was how she'd chew food and water in her mouth, then kiss me to force it into mine. That was just two months ago, when I was bedridden for three days afterward and couldn't even attend class.
If I didn't apologize now, she'd do it again with that same persistence. With that in mind, I forced out an "apology" through moans and ragged breaths, my mouth barely cooperating. But, as usual, she didn't want to hear it—she kissed me to shut me up, then ravaged me even faster and harder.
In her obsessive, brutal actions, my opinions didn't matter. Her fixation seemed worse than ever. The maddening pleasure made me faint and wake up dozens of times. I wasn't released until Sunday night.
Since I'd thoroughly "educated" Seon-ah to stop his "wrong behavior," I felt reassured for now. After wringing him out like that, he wouldn't be able to get it up for a while—even if another girl tried to force herself on him, it'd be impossible. That actually put me at ease.
Now, all that was left was punishing Min-ji for daring to show interest in my man. The shady agency recommended by the detective firm said the job I'd commissioned would be ready by next week.
Thanks to the generous allowance from my mother, Yura, I'd made a lot of money through stocks and investments. My father, a full-time investor, had taught me the ropes since high school. Even so, what I was spending now was just a fraction of my earnings. Money was great for living happily with Seon-ah—the more, the better—but ensuring he was mine came first.
