just a random question that came to my mind...
i realised that for Yamapi's lead roles dramas, like Proposal Daisakusen, Code Blue and Buzzer Beat,
NEWS/Yamapi didn't get to sing the theme song for the Drama,
whereas Arashi's Dramas, like Stand up!, Ryusei no Kizuna, Uta no Onii-san,
KAT-TUN Dramas, like Yukan Club, Tatta Hitotsu no Koi, Kami no Shizuku,
and also Hey!Say!JUMP Drama, Scrap Teacher,
the groups/member(s) get to sing the theme songs..
is it cox of how many members were involved in the drama etc?
or is it depending on different Broadcasting/TV stations?
or is it just depending on other stuff?
Sorry if this is inappropriate,
