抱歉温柔是我学不会的
[bào qiàn wēn róu shì wŏ xué bù huì de]
This roughly translates as 'Sorry, gentleness is what I cannot learn'. This expresses that while the individual wants to be gentle, they feel unable to adopt this characteristic or attitude. There's an apologetic sentiment here as if the user acknowledges it might cause some impact on others.
