By far in all the drama's I have watched, this is the most relatable one.
That feeling of liking some, watching them from a far; appreciating them from a far; loving them from a far. Its not exactly a new theme but when done correctly, its one of the most amazing love stories out there.
Loving someone not because you get something from them or expect to be loved in return.
But because your heart tells you too.
I really admire the writers for not letting Lou Zhi become like any other Female leads out there.
When she said that Innocence is important my heart just bled for her. When they fought in the rain, when she told him that he had already decided even if she explains herself.

It kind of reminds me of Monsta X's new song "Someone's someone" (although my heart is still breaking) it said
"We all wanna be someone's Wanna be someone's someone With somebody we can't live without" and the lines "Perfect with no reasons Reasons are for people you meant to lose"

You don't need reasons to love someone, you just love them.
