Hey...
What kind of dorama were they filming?
I thought schoolgirl doramas, especially those with a popular idol as the MC, all followed the same pattern: cute, silly, pure-hearted girl meets cold, hunky, brooding male lead, hates him at first, then falls for him, then redeems him with the power of love -- or something.
This one looks more like... I dunno, like they are filming "Virgins' Empire: the Dorama" and Sumika plays Yamada Kaoru.
Maybe Japanese doramas are evolving?
