After the bloodshed, for a long time, the hand that was reckless in my blood remained untainted.

This powerful couplet captures the ultimate pain of emotional betrayal. The poet laments that despite the speaker enduring a long period of emotional 'blood-shedding'—of suffering and tears—the beloved's hand, the hand that once played with the speaker's very lifeblood, remained untouched and pristine. It speaks to the deep wound of indifference; the person who caused the pain didn't even bear the stain of the suffering they inflicted. It is a profound commentary on emotional detachment.
