With his father's tone of voice and how he scrutinized Shen Ji Yun, Luo Yan was sure that the other's instinct, that seemed to have been turned off when it came to the two of them, had now finally awakened. He was now finally getting suspicious of their relationship. If they made a wrong step here, Luo Yan might not be able to attend the final tournament of Arcadia Cup next week.
That's probably not the best reason to prevent his father from discovering their relationship. But at this moment, that's his imminent concern. Because he knew that if he talked to his father and try to make him understand that he and Shen Ji Yun truly loved each other, he would eventually come around. But that's something that wouldn't happen in just a few days.
