Hamakaze and Nowacchi enjoy hugging the Rensouhou-kun while Amatsukaze enjoys wearing her sistership's clothes.

Minor differences in fashion taste; Amatsukaze buttons up the vest that Nowaki leaves open.

Also, Hamakaze doesn't have enough hair to utilize Amatsukaze's hair thingies, while Nowaki only has enough for one.

So, about Nowacchi's reaction while wearing Hamakaze clothes, should we tag this as breast envy.

I think whatever her reaction is implying depends on the viewer.

I like Nowaki's reaction when she's holding Rensouhou-kun.
