How to analyze Nana's behavior after the death of Lotus in Nana?

I haven't read much comics and comics, but according to my impression, Lian and Nana in Nana are lovers, and Lian is Nana's boyfriend. In any couple, if the boyfriend dies, it will definitely be very sad as a girlfriend (here refers to normal couples, excluding those couples with deep hatred and almost no love). As far as I know, Nana cares about lotus very much. She should love lotus very much, although there was a misunderstanding between them before, that is, Nana thought that she and Tai had more feelings than Lotus before, and later thought that Tai was nice to her because of Lotus. For me, this is really sad.

I always thought that Nana, who is careless and always cool, should not be hurt like this, but after careful consideration, Nana, like Nai Nai, and everyone else, is an extremely insecure girl, and she doesn't expect much from Lotus. Gossip boyfriend Lian said that Nana didn't need her help. In my opinion, this is both right and wrong. Nana is independent and strong, and doesn't want others to help clarify. But as a boyfriend, she didn't even say a word, let her solve it herself. In my opinion, Lian did a very wrong thing, and with the separation from her, Nana would feel unloved.

In the relationship between Lian and Nana, there is no right or wrong, but Nana must have feelings for Lian, and she must have been hurt after her death. Finally, although Lian left Nana, she persisted in her dream and continued her career as a singer, which was both Nana's own insistence and Lian's.
