forgot to say.
I like how they showed Rena getting a little closer to Iroha. First time Rena is in the roof, and they eat lunch with their backs to each other. Next time Iroha went there, Rena is sitting near the door with a chair for Iroha to sit on.
also poor Iroha, it's only a few days in school and she's already a "delinquent".
