Well, in fairness, Raintrying to get out of going to school altogether. XDAlthough Fara managed to convince her to go, she also mentions that they're behind schedule and Rain still hasn't even gotten dressed, let alone done her makeup or hair (and according to Maria on this page, Rain's still taking the time to text cryptic messages to her friends). It's very likely she won't get into school until classes have already started at this point. Maybe she'll even miss first period, but not because she planned to be late. She actually just wanted to play hooky.
