BTS first reaction to Blood Sweat and Tears (Japanese version) | The BU just got WILD (방탄소년단)

Finally for BTS Wings Week, I'm covering a #BTSreaction to both versions of Blood Sweat and Tears (the original and the Japanese versions). Today's is the Japanese version (   • BTS (防弾少年団) '血、汗、涙 -Japanese Ver.-' O...  ), and, well, as a new #BTSArmy, making sense of the #BTSUniverse just a lot easier and a lot harder.
