guys I didn't understand one thing at last did she stayed in the past or went back to the future ? the way they showed it felt like she was in the past all along..
so it's basically going to be when ml rejects fl she resigns herself from his company to not suffer from the rejection and to move on but of course our ml is not gonna like that just like any other ml in drama history at first he will chase to get her back in the company and eventually fall in love with her but fl will join another company and that's gonna sml's company where he will be and angel sent from heaven and then... the story will drag like 5 episodes and in the same episode both ml and sml will confess to our fl where she will get confused who she actually like at that point and of course she's gonna choose our ml welp there you go the story (sry for bad english)
