Wu Qing took another deep breath, looking at the torn spot, eyes wide open. Wen Nan held her fingers, feeling somewhat awkward. He said to start simple, and he wasn’t lying; he originally just planned to hold her hand. But who would have thought, Wu Qing was so nervous, her fingers tightly gripping the black silk, not willing to let go at all, even when Wen Nan tried to lift her hand, there was no sign of loosening. The black silk was also a semi-transparent, thin type, naturally not able to withstand such pulling. As it turned out, it seemed like Wen Nan had made a diversionary tactic. Wen Nan was thinking of how to explain this, but then heard a soft voice next to him saying, "Junior’s simple isn’t so simple after all. This level, I’m afraid Senior can’t handle..." Hearing this, Wen Nan decided not to explain, going along with it, he smiled and said, "Senior can even handle such high-level biochemistry courses, such a simple reward shouldn’t be a problem, right?" Wu Qing lowered her eyes, first looking at the exposed skin where her stockings were torn on her leg, then looking away, "I, I’m afraid I can’t..." She was just worried about not being able to handle it but did not directly reject it. Hearing this, Wen Nan smiled, "How do you know your potential if you don’t try?" Saying this, Wen Nan filled in another answer on the test paper, his handwriting flamboyant, one answer almost covering two answer boxes. Wu Qing glanced at the correctly written answer and then saw him put down the pen, turning around, his gaze seemed to wander over Wu Qing. A moment later, Wen Nan raised his hand, his fingertip gently landing on the button of Wu Qing’s shirt. Wu Qing’s breath hitched; when she bent over at the desk to avoid earlier, two buttons had already popped, and if one more was undone, her high-collar shirt with a hint of restraint would turn into a deeply sensual V-neck. Thinking of this, she glanced pleadingly at the person beside her, but opposite her was like a strict teacher, doing as he pleased, deftly unbuttoning the small white button. Initially, only a corner of black lace trim was exposed; now two half-hidden semicircles appeared. Wen Nan’s finger paused between those semicircles, his gaze settling on them, lost in thought. Wu Qing’s fists were clenched at her side, waiting for his fingers to drop, but the opposite side withdrew his hand like a good student, starting to fill out the answers with flying strokes again. One answer, one button. By the time the last button was undone, the circular chart was almost completely covered by his bold handwriting. Only the last two answers remained. Wu Qing’s chest heaved, secretly guessing that if the opposite had such a passion for "unhooking" and "unbuttoning," then the last two chances might target the black hook behind her and the single button on the waistband of her short skirt. In that case, wouldn’t she... be stripped of even the last shred of modesty... Wu Qing liked this junior, liked him so much that she’d long fantasized in private about various intimate scenarios with him, and it was precisely to turn those fantasies into reality step by step that she invited him over under the pretense of tutoring, deliberately donning such a suggestive outfit. However, her original plan was to take things slowly, to let him know her feelings, accept her, and then they could gradually move from the conference room to the couple’s inn next to the school, or perhaps the apartment she rented nearby... But now, just the second tutoring session, had progressed to this point, and it was in a conference room, a door away from a busy laboratory... This was far beyond Wu Qing’s own plans. Her "white little angel" felt overwhelmed, but the "black little devil" was eagerly anticipating what would come next. Pondering for a while, she finally decided to leave the choice entirely to the man opposite her. The circular chart was nearly filled with Wen Nan’s handwriting. He searched for a space for a long while before finally squeezing in another answer. Turning back, he looked at Wu Qing with a smile, "Senior, is it correct?" At this moment, Wu Qing was extremely nervous, unable to focus on his answers, merely nodding absentmindedly, "Mm, sure." This "sure" didn’t sound like she was confirming if the answers were correct, but more like permitting Wen Nan’s subsequent act of claiming his reward. Wen Nan put down the pen and moved close to Wu Qing again. Wu Qing still seemed very tense, but she turned her back to him, as if to make it easier for him to choose one of the two remaining "reward" points. Wen Nan chuckled, reached out his hand, and gently nudged Wu Qing’s shoulder, causing the completely unbuttoned white shirt to slide off her shoulder and drop to the ground. Pausing for a moment, Wen Nan’s fingertip gently fell on the button at her waist, right at the center. With her back to him, Wu Qing couldn’t see his actions, only feel the warm fingertip pressed against her waist, the friction against her skin urging her waist to twitch involuntarily. She thought the waistband of the skirt would soon be unbuttoned, but instead, the fingers slowly lifted upward, tracing her spine, inching toward the hook surrounded by lace on her back. The new black lace she bought had a single hook at the back, which could be undone with a gentle tug, like a loosely tied ribbon on a gift box waiting to be opened to reveal the contents. However, those fingers only lingered briefly on the hook behind her before continuing upward, gliding across her neck, finally landing on the hairpin at the back of her head. The black shark clip was removed, allowing her loosely gathered hair to cascade down, her previous authoritative presence softening as it gently flowed over her shoulders. Her long, wavy curls, styled into soft waves, slipped from her shoulders like a black veil, giving her a more gentle appearance. Wu Qing didn’t expect him to ultimately bypass the two "reward" points on her back and instead let her hair down, leaving her both relieved and slightly disappointed. While she was still a little lost in thought, he leaned close to her ear and whispered, "Senior, every space on that circular chart has been filled by me. There’s no space for the last answer, what should I do?" Wu Qing’s heart was pounding rapidly; she struggled to calm her breathing as chaos ensued in her mind, "If there’s no space, just... find a blank spot to write, I guess." Wen Nan received the answer he wanted and laughed, "Alright." Grasping the pen again, Wen Nan’s arm stretched over Wu Qing’s shoulder, sweeping her long hair from her front to her back, then thrusting the pen tip toward the "blank space" above her black lace, "Since senior said so, I’ll choose here then?" Black ink on the white "answer sheet" tickled Wu Qing’s heart like a feather, almost making her lose control. The one behind her, however, earnestly put the pen down and asked, "Did I get it right? If it’s correct, I want to redeem the last reward?" Unable to bear the suspense any longer, having reached this point, Wu Qing finally let go of the little bit of hesitation in her heart, stood up, turned around, and embraced him around the neck, extending an inviting gesture as she said proactively: "For the last reward, you can have the largest one..." Wen Nan paused slightly before smiling, "Since Qingqing Senior said so, then I’ll graciously accept." Thus, this "tutoring session" finally entered the main event. Things proceeded surprisingly smoothly, only partway through, driven by emotion, Wu Qing involuntarily leaned closer to Wen Nan, trying to kiss him. For some unknown reason, Wen Nan turned his head aside to avoid her attempted kiss. This caused Wu Qing’s emotions, about to reach their peak, to plummet halfway down the mountain. Wen Nan found his task at a standstill too as a result. He needed to find a way to lead her back to the summit. With that thought in mind, Wen Nan raised his hand to hold her waist, lifting her up onto the table, trapping her at the edge with his legs, using some tricks to aid her "climb" once more. When Wu Qing couldn’t hold back any longer, letting out a low cry, Wen Nan whispered into her ear with a smile: "Qingqing Senior, I think I forgot to lock the conference room door earlier. If you keep this up, be careful, the students outside might hear and come in to check." On hearing this, Wu Qing immediately raised her hand to cover her mouth tightly, her eyes wide with horror, staring toward the door. Wen Nan, of course, had locked the door carefully beforehand, merely said that on purpose. Seeing her witness such nervous behavior showed his plan had succeeded, his lips curled slightly. As footsteps faintly approached from outside, with Wu Qing’s body tense from nerves, Wen Nan seized the moment to add the finishing touch. The two simultaneously reached the "summit," as the system prompt rang in their ears— 9527: [Congratulations, player! Mainline Mission 2, current completion rate: 100%.]
