My Younger Brother Has a Bit of a Wild Side

[Younger man] [Mutually devoted] [A seemingly sweet and obedient, but actually obsessive and cunning younger brother VS a mature, commanding career woman] The puppy-like younger man turns into a wolf, pouncing on his older woman in no time. One day, Su Wan’s boss suddenly assigns an intern to her team, even specifically asking her, the design director, to mentor him personally. One second: “You’ve got to be kidding. I’m the director. Why would I mentor an intern!” The next: “Sure. I’ll do a great job mentoring him.” Song Xingzhou gazes at the exquisitely featured, sexy woman before him, a powerful possessiveness flashing through his dark eyes. … Su Wan blinks her lovely, almond-shaped eyes and leans in toward Song Xingzhou. “Little brother, do you have a crush on me?” His breathing grows slightly unsteady, and he answers in a low voice, “I do.” Seeing how serious Song Xingzhou looks, Su Wan’s heart tightens a little. Before she can collect herself, he presses her down beneath him. Song Xingzhou gently strokes her cheek and asks in a bewitching voice, “Do you like me, Sis?” A flicker of panic crosses Su Wan’s eyes, but she keeps her composure and says, “How could I not like such a well-behaved younger brother?” “Well-behaved? Younger brother?” Song Xingzhou curls his lips into a smile. Su Wan nods. The next second, a pale hand grips her chin, and a flurry of delicate kisses falls upon her.
