我不温柔却懂得爱你
[wŏ bù wēn róu què dŏng dé ài nĭ]
'Wo Bu Wenrou Que Dongde Aini,' means 'I am not gentle, but I know how to love you.' It shows a contrasting characteristic - on one hand, the person feels they're rough or ungentle, but deeply believes they can understand what true love should be. It implies an earnest confession toward a specific loved person.
