我不擅长挽留你却还是要走
[wŏ bù shàn zhăng wăn liú nĭ què hái shì yào zŏu]
'Wo Bu Shan Chang Wan Liu Ni Que Rang Yao Zou' translates to 'I'm not good at holding you back but still leaving'. It implies that even when someone is not skillful or hesitant in trying to keep a loved one from going away, there comes a time to say goodbye, showing resignation and inevitability with reluctance.
