一腔愚勇终抵不过一往情深
[yī qiāng yú yŏng zhōng dĭ bù guò yī wăng qíng shēn]
'Foolish Courage Ultimately Can't Match Sincere Love.' One has plenty of reckless and foolish bravado (such as rashly doing many things due to young love), yet still finds they're no match to true, earnest emotions over time, especially those towards love which tends to have an everlasting influence.
