Be Good During the Day! Bad Night! Stop Teasing My Yandere Brother

[Sister and brother + vest + sweet pet + 5 years age difference] Calm and wise female CEO VS soft and cute newcomer in the entertainment industry During the day, she is the young and courageous female president of the Lin Group, decisive in killing and telling the truth. He is a newcomer in the entertainment industry. He has a cute, handsome and sunny appearance, and his smile can be called healing. She is a Jiao Jiao Bao who has difficulty falling asleep at night and cannot look directly at the shadows in her heart. He is a gentle sleeping machine that embodies a tall image. She is a sister during the day and a baby at night. The little milk dog Su is so flirtatious that the female CEO can only surrender obediently and be willing to indulge in the tenderness of her yandere brother who is both milky and wolfish. "Sister, if someone bullies you, I will help you fight back." "Sister, if someone is pestering you, I will help you deal with him." "Sister, if you can't sleep, how about I massage you and sing to you?" "Sister, can I... Can I call you baby?" He thought that his yandere brother had been in love for a long time, but he didn't know that he had planned it for a long time.
