Tiredness is sour, loneliness is bitter, pain is spicy and sadness is salty; As long as you adjust these things and eat them in your stomach, you will eat rich flavors, and life is just like this. It is sweet when you look at the person you like; It is sweet when you hold hands with the person you like; It is sweet to be envied; It is sweet to have memorable memories; All surprises in life are sweet.
