会心 is a verb-object compound meaning 'to have a meeting of minds' — the understanding that passes between people without words. It's most often seen in the fixed phrase 会心一笑 ('to exchange a knowing smile'). As a separable verb (离合词), you can split it: e.g., 他们只见过一面，却会过一次心 ('they've only met once, but they shared a meeting of minds').
