He will understand me only gradually over time; right now, he has no idea what truly lies within me.

This couplet captures the quiet truth that human beings are vast and layered, not easily mapped in a single encounter. The poet gently points out that understanding someone's inner world takes patient time and genuine intimacy; you cannot skim a person like a headline. Right now, the companion only sees the calm surface, unaware of the deep storms, joys, and complexities hidden beneath.
