The first time Wendy met Irene, Irene was wearing pink. The first time Wendy saw Irene cry, her eyes weren't a puffy red. Instead they were a puffy reddish pink. When Wendy first called Irene cute, her cheeks turned pink. When they debuted, Irene's hair was dyed pink. But when Irene held Wendy's hand and whispered to her, you are mine and only mine, Wendy's cheek flushed a light pink.
