JYJ3 Note: Koike Teppei is one of the 2 singers of the duo WaT and has acted in J-dramas in the past, too.
He is currently performing as L in the Japanese Musical version of ‘Death Note’.
In particular, to Kim Junsu in the role of ‘L’
I think that his back is unbearably in pain, which results in a posture like a hunched-over cat, thus
Please put forth strength and enjoy ‘L’
