I watch it second time it completely change the preceptives of how i saw the story .. I reality was Wang Quan Sheng never loved Huang Yu Xuan . Wang was gay . HE try to kill himself so li zi wei took over his body when lizi was in coma use his body to change things . Wang inner soul already died so lizi was split into two they can't exist together so wang Quan took decision to destroy himself .
Huang loved liZi not Wang . LiZi loved Huang not Chen Yu . I love of Huang and LiZi made the changes in their dimensions and they went into deep loop . I loved the ending how different world is created now Mo Jun and Chen seem to be close start their own love story that way the loop of dimensions end there as Chen no longer need LiZi .
Now another dimensions start may be somwhere in future another loop will start but this time LiZi and Huang ANYONE else wouldn't get involved in future . I love everything about it . As i had second lead syndrome for Mo jun to be with chen it seem like it went kinda at last . This drama really mind blown me Kudos to actors , Directors and Writers . Everyone's acting was Top Noch
