People often talk about love-sick men and resentful women. The ancients have explained it very clearly. A love-sick man refers to a man's infatuation in love and his loyalty to his feelings, which only he himself knows. A woman can fall in love with several men in her life, while a man can fall in love with multiple women at the same time. However, women do not know that men actually fall in love with only one person in their entire lives!
A man's truly pure love only happens once. When that love comes, he will go all out. When that love is gone, it will never come again. That love was too deep, and the pain was also too intense.
