The nickname translates as 'Old Lovers Torture Heart, New Lover Enjoys Songs That Torture Heart, Old Lovers Enjoy Listening'. It seems the user is expressing feelings tangled in multiple layers of old affection and new affections. Perhaps hinting at how these different loves and breakups continue to affect his heart, or it could reflect the difficulty of moving forward with new love while still carrying old pain or sentiment in a cyclical manner.
