Shh! to Pursue Your Sister, You Must First Pry into the Fake Brother-In-Law's Corner

Ignorant and clingy love-brained puppy × gentle and alienated sister [Wife Chasing Crematorium/Childhood Sweetheart/Nianxia Sister Dog/he/sc] Cheng Chun and Ji Jinchen grew up together as childhood sweethearts, and their relationship was so good that they ate and lived together. But Cheng Chun has a secret, that is, when she was in love for the first time, she fell in love with the boy who had been following her since she was a child and took her away from the rain. So, Cheng Chun lowered his eyes and said softly: "If there is a suitable person of the opposite sex of the same age, please introduce it to me." But Ji Jinchen took it for granted that it was enough for Cheng Chun to have him by his side and didn't take it to heart. Later, Cheng Chun was approached by an admirer. —— Ji Jinchen was happy as a child, had a good personality, a superior family background, and was handsome, but he had never been involved in any scandals. The reason is that he has been following Cheng Chun and shouting about his sister since he was a child. He was so attached to his childhood sweetheart that everyone thought they were together. Ji Jinchen has been with her for more than ten years without any problem. He firmly believes that being interested in the sister he grew up with is something only animals would do. Until one day, he discovered that Cheng Chun had an admirer behind him. Ji Jinchen looked at the two people standing together and felt that he was sick. Otherwise, why would he feel so uncomfortable? He asked: "Why is my sister always with him?" Cheng Chun said: "You introduced him." Ji Jinchen endured it, thinking that Cheng Chun had the freedom to pursue his own happiness. But as soon as he saw her with another man, Ji Jinchen felt like he couldn't breathe anymore. He leaned over to her and put on the most pitiful expression: "Sister..." Just be beasts, there is no one more familiar and suitable for a mistress than your childhood sweetheart.
