Everything is real the anxiety, the trust issues, the uncertainty, we know these, we lived through these atleast once but even when you know what's gonna happen next, its still surprising.
The portrayal of each character is superb i can literally feel everything they are going through...
Since the story mostly tells us how Nabi is thinking and feeling we can relate to her to some extent but I think if jae eon's side of the story is also revealed we could definitely feel him too. Maybe he's going through same feelings as nabi maybe he also waits for her call/text maybe he also misses and dreams about her, who knows... Or maybe it was a love at first sight for him but he himself doesn't know.. maybe... Just maybe!
