末日最无心末心最无情
[mò rì zuì wú xīn mò xīn zuì wú qíng]
The phrase implies a heart as indifferent as the doomsday; it portrays a mood of detachment and apathy, suggesting that everything is meaningless as if it's at the end of the world. Both 'most unintentional' and 'most indifferent', this name delivers the feeling of someone who wishes to be detached and not care about the feelings of others or any outcomes.
