After Marrying My Fiancé's Brother

The paranoid, dank and crazy male protagonist x the honest-looking but yandere female protagonist (1) Ruan Jia's fiancé died while diving. The marriage of the Ruan and Zhou families is inevitable. Therefore, the Zhou family proposed to let their fiancé's brother Zhou Jincheng take over the marriage instead. Ruan Jia thought that a cold and arrogant man like Zhou Jincheng would not agree to such a ridiculous proposal. Unexpectedly, the reply from the Zhou family was that the marriage would continue. (2) Zhou Jincheng and Zhou Shengyu are twins. But their personalities are completely different. Zhou Shengyu is a warm jade under the moon, upright and reserved, holy and dust-free. Even in bed, when others play with him, he will only put his cheek in Ruan Jia's hand and look at her with eyes full of spring water. And Zhou Jincheng was born with cold snow. He is cold, awe-inspiring, solemn, and aloof. Ruan Jia rarely interacts with Zhou Jincheng. In her opinion, a restrained person like Zhou Jincheng will never lose control. However, before Ruan Jia knew it, Zhou Jincheng had lost control and gone crazy countless times. I don't know when he started to have synesthesia with Zhou Shengyu. The beating around his ears, the scorching temperature, and the lingering aftertaste like a rising tide, tortured him almost crazy. He traveled to other countries in an attempt to control the beast in his heart. However, all he got in return was night after night of humid and unspeakable struggle. (3) Zhou Shengyu is dead. Zhou Jincheng returned to China to take care of his brother's funeral. His parents asked him if he could accept marriage with Ruan Jia. I haven't seen anyone yet, but I only heard the word Ruan Jia, and my desire was rolling. He knew he was completely finished. (4) Zhou Shengyu is back. He came back alive. (5) Zhou Jincheng found hickeys on Ruan Jia's body that did not belong to him. Purpose: Loving others is like growing flowers
