How did Zhao Youbao find out that he liked Wanle?

Zhao Youbao found out that he liked Wanle because Liu Yucui left Zhao Youbao’s company. Zhao Youbao picked up his mobile phone and sent Wanle a few text messages. He wanted to know if Wanle still liked him, and Wanle received the text messages. Even though Le was very reluctant to Zhao Youbao's engagement, he still held back his true words, hid his tears with each Chinese character, and pretended to be indestructible. After Zhao Youbao saw Wan Le's cold reply, he felt even more uncomfortable. He finally understood that he had always cared about Wan Le.
