wholeheartedness; sincerity

Today, women's only consideration in marriage is probably if you love him or not, if he loves you or not, whether he is sincere and heartfelt towards you, whether there will be pressure with him, whether there will be happiness, and not what his possessions are!

If he says "I love you" all the time he doesn't mean it.

You have helped me so much, I'd like to express my sincere gratitude.

But having someone is already good in and of itself, and if they treat you with sincerity and love you from the bottom of their heart, then you really can entrust your life to them.

I say this from my heart.
