No synonymous idioms come instantly to mind, but these expressions mean:
1. Face the music. To face the music means to recognize clearly the reality of a situation, to confront the consequences of an action, and begin to act in a responsible way (to repair harm, or begin to solve a difficult and previously unaddressed problem). After years of poor health choices, Ellen was in danger of becoming seriously ill. Her doctor told her she had to face the music: stop smoking and get some regular exercise.
One very similar idiom is: 'Wake up and smell the coffee.'
2. Wrap [someone] around one's little finger. This expression implies that the 'wrapper' () has the power to command the 'wrappee' (the one being 'wrapped' ). It is understood to mean that this power has been gained by charm, not force. Silvia has her grandparents wrapped around her little finger. (They are willing to do anything to please her.)
One similar expression is 'to have [someone] at one's beck and call.'
I hope this is helpful. All best wishes,
