Yeah! I realized the same! In the first episode of season 2, when they finished fencing, Li Yizhou called Wen Li and besides telling him to prepare the press conference, he told him to "delete the medical history", which made me think that he was going to make the "you have leukemia" story, but since she already approached him, he stopped it.
Another reference was at the end of episdo 3(?) or 2, when they asked him why he joined the reality show and he said "earn money for mumu"
But to be honest, I have this opinion: this season is the drama that Jia Fei wrote.
If I'm not wrong, Jia Fei at the end wrote the story of them, and Xia Lin said something about it, and I remember it because Wen Li didn't agree because he was "different", also in this season, when she first met Ling Yizhou, she said "this is not as elegant as in my stories" but if we compare it to first season, this one is more aesthetic and minimalistic, like many other dramas.
And may we talk about the new soft, semi-stalker Wen Li?
