The heavy rain of the whole night washes the city clean. Crystal drops slip off the leaves, and the fresh air is refreshing. Yu Fei wakes up from the nightmare, opening her eyes and seeing the cold-toned household style, feeling stunned for a second, and the memory of last night emerges in her mind little by little.

Ko Chen, the heavy rain and Gu Yi

With a headache Yu Fei covers her forehead with her hands, and her thoughts are chaotic. She stands on the ground with bare feet, and her skin feels cool from the foot floor. For a moment her sights blurs, and Yu Fei shakes her head, waiting for the sight to becomes clear, then she walks into the bathroom with her muddled head. Seeing the woman with the red face in the mirror, Yu Fei is stunned, is this person herself? She raises her hand and touches her face. The woman in the mirror does the same thing and her hands feel hot.

Even after being taken care of by Gu Yi last night, Yu Fei inevitably has fever. After washing in dizziness she walks out of the room. The room is empty and no one is here, but there is a note on tea table by Gu Yi, which is full of all kinds of matters needing attention. Yu Fei reads it line by line, and she can’t tell what she feels but she feels warm. She was planning to go home, but according to her current state of health, staying at Gu Yi's home is the safest option.

Daring not to take anti-fever medicine, Yu Fei can only cover her forehead with a towel soaked in cold water over and over again. Because she is not very conscious, and after doing this several times, she is out of strength, lying on the sofa limply and falling asleep soon. Yu Fei sleeps soundly in Gu Yi's home and doesn’t know that Ko and Gu are at a bloody war at this time.

After receiving Gu Yi's instruction last night, the staff of the planning department stayed up all night to turn over and re-worked out all the cases. Gu Yi examined them carefully, pointed out a few minor flaws and let them modify them a little. Until the new proposal comes out is Gu Yi relieved. Glancing at the time at the lower right-hand corner of the computer, he realizes that it has been noon already. His full attention is devoted to work and forgets the time.

Yu Fei is alone at home and maybe she wakes up. Gu Yi frowns and can’t help but worry. When he is about to call her, the secretary suddenly rushes in even without knocking at the door, “Mr. Gu, something happened!” Gu Yi frowns deeper and looks at him with his sharp eyes, which makes the secretary calm down immediately. Although Gu seems mild-mannered in daily life, when one gets familiar with him he will know that he is nothing like what he shows. He is actually a scheming man!

The secretary calms down and clears his thoughts, then reports to Gu Yi in a calm tone: "Mr. Gu, Ko’s company took a step ahead of us to send a new plan, and cooperator even didn't look at our plan and signed the contract with Ko’s company." The secretary's voice gradually becomes lower, by the end he has lowers his head completely, and is afraid to look at Gu Yi’s face. Gu Yi scowls with insidious and ferocious eyes like a representative from hell. They only spent one night. How could Ko’s company happen to change their plan before them?

“Call all the people in the planning department to here!” Gu yi controls his voice but people still can feel his fury. Being in business for so many years, he will never tolerates a spy that sells company information around him. Few minutes later, when the manager of the planning department takes all the staff to the office, Gu Yi sits in the office chair with his back to them, and they can feel his rage just from his back.

"Mr, Mr...Gu..." The manager shivers and says, and as soon as the word “Mr” is just out of his mouth, a stack of documents flies towards him, sweeping by near his ears and falling, scattered on the floor. He is so scared that he immediately shuts his mouth. Gu Yi turns around, sweeps over everyone with fierce eyes, trying to find a flaw in their faces, "I only ask once, who has leaked the company secrets?"

The silence in the office is so quiet that even the sound of the needle falling on the ground could be heard. Gu Yi stands up from his seat and says with a low voice, “No one admits, right? Well, I'll give you a day, either to find this mole or to get out of here all !” Gu Yi is really angry this time, and the manager's forehead sweats and the shirt behind wets. After all the people of the planning department go out, Gu Yi dials the inline phone to call the secretary in. Now the news that the case lost has spread throughout Gu's company. Everyone knows that Gu Yi is in a bad mood like an active volcano that may erupt anytime.

“Tell the monitor office, send the surveillance video of the planning department to my computer.” That mole who has secretly contacted him is definitely afraid after he just lost his temper, and all he has to do now is wait patiently for his falling into the trap. He will figure out who dared to betray him. Gu Yi spends the whole afternoon looking at the surveillance video on the computer. To his surprise, no one in the planning department had any unusual performance except that they all looked more careful. It seems he has underestimated this mole chosen by Ko Chen.

At the other side of the city, in the Coyote building, Ko Chen looks at the latest news in the phone screen which was sent by "cat". “He found it. Investigating.” Ko Chen presses the home key with a casual smile, then the screen turns black and those six words of the text message disappear together. Ko Chen plays the mobile phone with interest. He is not surprised that Gu Yi found "cat ", and if he were not found, that would be unimaginable.

Although Gu Yi has perceived that, the mole isn’t exposed. As Ko Chen knows, Gu Yi is unlikely to find out who is this guy. Since Gu Yi appeared beside Yu Fei for the first time, he found the "cat " and ordered him to keep hiding in Gu's company until last night Gu Yi made a temporary decision. The"cat" thought it was a good chance so he contacted with Ko Chen to tell him that Gu would re-do all the case.

Because of this, Ko’s company can step forward to change all the cases and take them all, taking away Gu's chance. Ko Chen's eyes are clod. He has never lost in his business, and Gu Yi has no ability and opportunity to compete with him and he will not have these in the future. Besides, the man has been challenging his bottom line.

Ko Chen's bottom line is always only Yu Fei.
