Both the dramas have independent and feminist female leads who are actually smart. (also funny) The main characters relationship begins with a fake/marriage of convenience and gradually develop feelings for each other. Kind of like a slow burn but not too slow.

In both See You Again and Closer to You Female lead is dead in current timeline thus, our main leads travel back in time ie, their high school days to save their lover.

See you again and Blue birthday are both time travel drama which is also related with a camera. Both of the drama are also based on high school.
