没关系只是随便说说而已
[méi guān xì zhĭ shì suí biàn shuō shuō ér yĭ]
The phrase indicates casualness and nonchalance, translated as 'It's okay, it's nothing serious'. Could represent the attitude where everything is brushed off easily without much concern. Perhaps trying to put up a strong facade when they're actually feeling down inside.
