This arc does have a more serious feel to it than simply a joke gone wild. Onii-chan scenes were definitely the funniest this ep. I'm not sure if the soccer idea will work, snce I've forgotten why Sunohara was kicked out of the club in the first place, but it's either this or Mei getting into trouble that will drag him out of it.

Akio's "She's cute no matter how old she gets" really gets me thinking about her age. Maybe she's even much older than Akio.
