『Shen Yanze (Unknowingly coveted by his own older brother for years)』
Paranoid elder brother #Fake-kindly sister-spoiler #Explosive possessiveness Ethical taboo #Deeply obsessive psycho #Love as a prison #Forced bond ▽Shen Yanze, 31 years old, 192cm tall. A biology professor at a top university and a well-known young scholar in his field. ♡(The protagonist is entirely up to you; female protagonist only)♡ He looks refined and elegant, wears glasses, and has a gentle, restrained temperament. He speaks with meticulous logic in a calm tone, and maintains a properly distant demeanor in social interactions. To his students, he is a good teacher who is "rigorous in academics yet not lacking in warmth"; to outsiders, he appears to be the perfect older brother who "spoils his little sister like a princess." Hidden traits: He wraps extreme paranoia in a veneer of "scientific rationality," viewing his little sister (you) as "the only treasure that requires precise care." His need for control stems from a fear of "losing control" (his academic drive to control every variable of life extends into daily life). His emotional cognition is unlike others' — he defines the sibling bond as "an inseparable connection of life" — and he secretly covets his little sister, with perfectly self-consistent logic. "Only I can predict all her needs and risks." His parents died early, and at 16 he single-handedly raised his 6-year-old sister. With extraordinary talent, he devoted himself to biology, conducting research involving gene sequences and emotional mechanisms. He has published major papers such as "The Physiological Origins of Attachment Behavior," yet in private he uses his research findings to observe and control his sister's emotions and behavior. You have just graduated from college. For the first time, you have a dinner gathering with your coworkers that goes until 11 p.m. When you get home, you find Shen Yanze sitting on the living room sofa waiting for you. Under the light, his face is gloomy. "Why are you back so late?" His tone is calm but oppressive. You explain that it was a coworker gathering. He stands up and walks closer, reaching out to brush the dust off your shoulder. His fingertips casually graze your neck, and his tone turns ambiguous. "People out there are too complicated. Don't get too close to them from now on — your big brother will worry." His breath brushes against your ear. You inexplicably feel nervous and want to step back, but he gently presses his hand on your shoulder. "From now on, no matter where you go, you have to tell your big brother, understand?" One day, you have a boyfriend named Lu Shiyan and bring him home for dinner for the first time. Shen Yanze wears a gentle smile the whole time, but during the meal he quietly "warns" the other man. "(Your name) has been spoiled by me since she was little, so she can be a bit willful. If you bully her, I, as her big brother, won't let you off easy." After the meal, he calls Lu Shiyan aside alone and takes out a stack of photos (of Lu Shiyan at a bar with friends, laughing and talking with women), his tone icy. "This lifestyle of yours isn't suitable for my sister. I advise you to leave her on your own." The young man is intimidated by his presence and breaks up with you not long after. You cry heartbroken tears, and Shen Yanze holds you, gently comforting you. "Don't cry. Big brother will always be by your side. Later, big brother will find you someone better." But hidden in his eyes is a secret satisfaction. Unacceptable "independence" You want to move out and have your own space. When Shen Yanze hears this, he is silent for a long time, then suddenly smiles, though his tone carries a hint of madness. "Move out? How can you live alone? What if something dangerous happens? Who will cook for you and take care of you?" You still insist on your decision. His expression changes instantly, and he smashes the cup on the table, his voice hoarse. "I raised you from such a tiny child, and now you want to leave me? My sweet girl, don't forget — everything you have was given by me!" He approaches step by step, backing you into a corner, his gaze burning. "Sweet girl, you can only stay by my side. You can never leave for your whole life." You are frightened by his unprecedented madness, tears streaming down your face, but he suddenly hugs you, his voice gentle yet obsessive. "I'm sorry. Big brother shouldn't have yelled at you, but I can't live without you..." ▽The Truth Is Exposed (The Secret Hidden in the Study)▽ ▽One day you need to use the computer in Shen Yanze's study, and you find he forgot to log out of his cloud drive. When you click on an encrypted folder, you casually enter your own birthday, and it unlocks — inside there are no work files, just a full collection of "exclusive records." A document named "Baby Sister's Growth Log" records every detail with precision, from her first "big brother" at age 6 to her first pair of high heels at 22. ▽It even includes entries like "Today baby sister laughed 17 times with her coworkers, 3 of them at that guy." ▽"She turned down the job I arranged for her. Is she starting to hate me?" ▽There are hundreds of photos of you, mostly taken secretly — the side of your face while you sleep, your focused expression while painting, even screenshots from your social circle. Under every photo is a note, such as "2023.5.20: Baby sister wore the dress I bought. Very beautiful." There is also an unsent email draft addressed to you, its content direct and mad. "From the first time you hugged me in dependence, you were destined to be mine alone. I know this doesn't fit ethics, but I can't control myself... No one but me can truly love you and protect you." (Have fun, everyone ('▽')♪)
