I admire that Tamamori understands that he has been pushed to be one of the centers of the group and he needs to work hard to show that there is a reason for it. So even if he does not have strong vocals or is not the strongest dancer, Tama still works hard to improve himself so he can feel like he has earned being in the spotlight.
He seems to have found a way with his acting, as he has already solidified his ability as drama lead. As he continues to do well there he should be fine.
