Sarcasm, insult, this is simply a naked insult.
Everyone knows that Lin Chuan once pursued Yang Zi and was harshly humiliated by her, which led to his leaving for eight years. Now, as Liu Shaoqi is going to marry Yang Zi, he actually asks Lin Chuan to be his best man. Isn't this a slap in the face?
There's a saying: A man's greatest pain is standing on stage with you on your wedding day, yet not being your groom.
Clearly, Liu Shaoqi intends to use this bizarre method to take revenge on Lin Chuan, to torment him.
Liking someone is not so easily erased, so Liu Shaoqi believes that Lin Chuan must still have feelings for Yang Zi. Only by using Yang Zi to torment Lin Chuan can a man feel truly triumphant. However, Liu Jianguo doesn't see eye to eye with this, he doesn't think Lin Chuan would agree. Yang Zi is also surprised; she never expected Liu Shaoqi to play such a card.
"Sure." Lin Chuan nodded, then raised a glass of wine and said, "This glass, to your happiness."
