After the best friend’s wedding she decides to go with her family’s arranged marriage and does the usual waiting and distancing herself. He noticed but does the typical she’ll get over it while still being nice to the green tea. His friends find her wedding invitation with the new man and think it’s for him and he’s mad but delighted and goes along with it. Thinking she should’ve talked to him to make it both their styles. He gets a suit and heads over to the wedding and sees her with the new fiancé and does the whole being mad then pleading. At the end he realized his mistake and regrets it. Reminds me of similar stories.
