I wasn't expecting that she'll experienced an intimate relationship with all of them. She really slept with all of them, although it can't be said to be very willing but it can't be called r*pe either. How should I put this? The MLs, except for one, doesn't accept rejection very well. They are domineering and wants to own the FL, regarding of what she want. They'll do everything to keep her.

• Shen Yanli was domineering and forceful. He doesn't accept rejection at all. However, it can be said that he's direct. Unlike the other MLs who are double faced, it can be said that he is kinda direct when it comes to what he wants and what he dislike.
• Fu Xi was as domineering as the former but more subdued. He's a smiling tiger. However, it can be said that although he's like SYL somehow, he's more patient. He knows how to bid his time. He'll stop once he feels that the FL was overwhelmed. But he's not that kind either as he's willing to use some unscrupulous methods in order to keep her.
• Wen Shaohan, the love interest who never got the chance of redemption. Although he doesn't appear as much as the previous two, it can be said that hus obsession towards the FL was no less than theirs. He was hypocritical. He looks gentle and all but just as others described him, he has low mortality. He can take the FL away without caring about his friends (not like the other two cares though). But Wen Shaohan was just an obsessed character without redemption.
• Pei Jue was the ultimate male lead. Unlike the others, he doesn't came off as someone obsessed or totally possessive over the FL. In fact, he's usually indifferent to the FL, unless she's in trouble. But he's the most sane, most patient, and probably the most normal among the four. He isn't like the others who are domineering or clingy. He was mature and gentle. That's why although the FL got involved with the other three, it can be said that she only fell in love with Pei Jue.

Out of the four, Pei Jue doesn't need a redemption arc and like what I said earlier, Wen Shaohan doesn't have any redemption scene or second chance. So only Fu Xi and Shen Yanli got their second chance.

• Shen Yanli "saw" what happened to all the alternative endings (such as when the FL got married to Fu Xi after they lost their memories, or when she got married to Pei Jue, or when she divorced Fu Xi). After that, it quite feel good that his choice was to give freedom to the FL, the thing she wants the most. Although his story with the FL was open ending, it was touching how he became patient. He loves her but she loves freedom, so he gave it to her. Even when he missed her, he never disturbed her but instead, watch her quietly.
• As for Fu Xi, he saw the alternative ending in which their marriage ended in divorce then the FL married Pei Jue. So when he "woke up", he protected the FL from everyone that can harm her— SYL, WSH, his family, etc.

Anyway, for me, Shen Yanli's choice was greater though. After all, they got together with the FL because they forced her, so giving what she wants (which is freedom) while protecting her silently is the greatest choice for me.

Nothing can escape fate. I think this is the core of the plot/conflict. The world consciousness will do everything to correct the so-called plot. Therefore, the FL experienced 3 phases. The first is when she just transmigrated and changed the perception of others towards her with her own attitude and sincerity. The second was when she was no longer hated and got involved with 3 of the male leads, and so, a system appeared to wipe the memories of the MLs and reset it to when they still dislike her in order to "correct the plot" in which the MLS should not be involved with the vicious female supporting character, only with the real FL. And then the third happen when she got married with FX and the others recovered their memories. So then she was, once again, transported to the timeline of the original story in which, the vicious female supporting character did wrong and was thus, kicked out of the villa.
