Review Detail of Jasmine_Belfrom in Sweetheart Must Love Me

I really like this comic but what confused me was when they went to the flashback. It's it just me? The flashback seems to throw the story development into chaos. Where does the flashback end? Is it from when the flashback starts until the end or does it end at the b4 the nightclub part where Yu Yin calls her?... I'm assuming it's until the end because she saw a picture of Qingfeng's sister in the nightstand previously. If it is from when the flashback starts until the end... is that what happened 5 years prior to him finding her again? If that's the case when's the first time Qingfeng meet JuiJui? Did she pretend not to know Qingfeng when she saw him again? Did she runaway the first time when JuiJui found out she was a mistress or was that the second time? When did she meet Li Sicheng? When Sicheng took her to the hospital was that history repeating itself or was that when she was pregnant the first time? Or did he pretend not to know her when they were engaged? How did she loose her loose her memory? Was it Yu Yin?
