The bitter taste is already a familiar taste for Nan Xuyi. Even when he drinks coffee, he always drinks ESPRESSO, the bitterest espresso. He has not felt anything wrong with this for twenty-eight years. It wasn't until the pastry chef next door suddenly broke into his world and brought a little bit of sweetness to his world of only bitterness. Later he realized that sweetness is addictive. Nan Xuyi confessed his love to Wen Ye for the first time. He said: "Everyone has a hobby that they can't give up the most, and the one I can't give up the most is Wen Ye." You are the one I can't give up the most, and your hobby is also you.
