The net name conveys two sides of loving someone: 'A heart stays well-behaved for you, another just does enough for you'. The first phrase means a part remains faithful to this love while 'another part keeps it in check and doesn't get overly obsessed with you'. It reflects complexity when someone loves deeply yet rationally controls those emotions.
