Hello, in Chapter 4 where you have to talk with the Director on the mobile phone there is a game breaking bug where the director isn´t responding with an answer and it doesn´t go on. Please help

I somehow stumbled upon this game and want to play this because of the time traveller. However, in the store page description, Shen Xuanqing is repeatedly referred to as a 'she' making it very difficult to understand the paragraph. Also this part sounds wrong, that he has 'a disdainful attitude towards honesty and integrity'. I would have thought the opposite would be the case with him, no? The developers don't seem to be active on the forum either, which is disappointing. One of the reviews also mentio...

I´m on the Route for Ye Zhiheng and after Chapter 3 The Heartmeter is full but when I start Chapter 4, the Heartmeter isn´t full anymore and I checked all the Choices till the End of Chapter 4 but the Heartmeter doesn´t go up all the way. Can someone help please. In other words how do I get the Happy Ending with him...
