Finishing school in japan isn't that imprtnant there are international schools in Korea. If she does join kpop it is probably because: a) It looks like AKB is falling apart b) Kpop is getting to be a bigger and bigger industry c) She wants to be known for her talent? There were rumors after PD48 about her getting picked up by JYP. It is very likely since they have a project for a japanese girlgroup that is a mix of the kpop and jpop style. Kpop teaching and training but the jpop growing up and learning as an idol. They are basically going to get the lessons and teaching while they are already promoting as idols I think. For that Erii would be perfect.
