爱的越深刻越容易失控
[ài de yuè shēn kè yuè róng yì shī kòng]
It implies that the deeper the love is felt between two people, 'the easier it becomes uncontrollable'. The depth of feelings may result in emotional outbursts, actions taken without thinking or other uncontrolled reactions when things take a bad turn, emphasizing the overwhelming power true love can hold over someone.
