After Claire and Fein agreed to go to the concert together. Claire told Dior that he couldn't go to the concert with him. He still argued that Valerie asked to accompany her shopping.
Dior, who knew that Claire was lying, tried not to say anything. He thought positively, maybe Claire didn't want to go but was using Valerie as an excuse.
"I'm sorry, maybe next time we can go. Unfortunately this week we can't," Claire said.
"It's okay, I can understand. Maybe next time," Dior replied as he forced himself to smile, even though he felt very disappointed that he couldn't go with Claire.
Claire himself felt bad for his best friend, he refused Dior's invitation to go to the concert but instead went with Fein. Even so, he really wanted to go with Fein alone because Claire felt that this would be their first date together after they became lovers.
