起初⋯⋯,⋯⋯才⋯⋯
起初⋯⋯,⋯⋯才⋯⋯ — at first …, only later …
Pattern
+ + + +
( ) can be left out · other words may come before, between and after
How it works
起初 sets up how things stood at the beginning, and the 才 clause reports the later turn — with 才 stressing that it took until then. The pair works because the second state contradicts the first.
Examples
起初我不同意,后来才明白他的用意。
Qǐchū wǒ bù tóngyì, hòulái cái míngbai tā de yòngyì.
At first I disagreed; only later did I understand what he meant.
起初大家都不看好,直到成绩出来才服气。
Qǐchū dàjiā dōu bú kànhǎo, zhídào chéngjì chūlái cái fúqì.
At first nobody rated it — not until the results came out were they convinced.
