My Cold Older Brother Is a Jealous, Brooding Type

■ Forbidden romance | Three-year age gap | Paragraph comments are open ■ Brooding, jealous married man x coddled, oblivious human log Growing up, Chen Yao didn't like Chen Fangshu, the "brother" she was forced to live under the same roof with. He was always so clueless about romance and utterly unresponsive. His personality was strange, too: taciturn and gloomy, like the least popular cold-blooded creature in a terrarium, cold and clammy, silently watching the outside world from the shadows. Chen Yao, always ignored, assumed Chen Fangshu hated her, too. Before long, Chen Yao realized there was something off about her brother. Her missing hair tie turned up under his pillow, and she often heard him mumbling her name in his bedroom. Whatever she did, she could feel a gaze fixed on her from behind. The night she announced she was dating someone, Chen Yao was pinned against the wall by Chen Fangshu. Her usually composed brother stared at her, his eyes fixed and intense, and ordered her word by word: "Break up with him." "Chen Fangshu, aren't you getting a little too involved?" "You aren't right for each other." Chen Yao glared at him and shot back furiously, "Then who am I right for? You?" The man was silent for a long time, his dark eyes resting quietly on her. In that moment, Chen Yao's hair stood on end. Because those eyes had clearly given her an answer: yes. And the burning gaze fixed on her felt all too familiar. A few things to know: 1. The leads are not related by blood or marriage. 2. They are each other's first. The younger sister dated someone at school for a few days, but they never got intimate. She was young and didn't understand love, and they broke up soon after. Her brother gets jealous, which helps set things in motion. 3. The male lead is brooding and sensitive, and can be incredibly clueless and unpleasant in some situations. The story includes scenes of him losing control and a twisted relationship (important). If that's not your thing, please drop the book. 4. The leads don't get intimate before they are adults.
