Feels like author is unnecessarily dragging the story. Sometimes reading this gives me only irritation. If she's so worried why not just do a maternity test with tangtang? Wouldn't it solve all the problems? And si yehan pretending to not know her is even more dumb. She won't go back to China in any case so why lie??? Doesn't he know her at all?
As for the real villain of this story is Nie Linglong.The fake worriless mentioned that Linglong's ambition is to bring independent state under her feet and she's extremely dangerous. Maybe the real worriless saw and known this that's why she wanted to leave the independent state and asked Si Yehan to help. Otherwise there's no way the arrogant Bro flattop would get frightened.
