Upon release the title song, Just Another Girl charted in 34 countries on iTunes, and the album reached the top of the charts in the rock album category in twelve countries and regions, namely in Japan, Taiwan, Thailand, Malaysia, the Philippines, Singapore, Hong Kong, Indonesia, Barbados, Lithuania and Slovakia.

Immediately after the release of the album, Jaejoong embarks on his Asia Tour, the first stop being the COEX Hall in Seoul, with audiences reaching over 14 000 in numbers.

The sold-out concert in Seoul occurs for 2 continuous night, with appearances from well-known artists like Kim Bum Soo and Gummy (singer) (a labelmate).

Amidst all the concert blues, Jaejoong attended various interviews in news outlets and radio shows in Japan, a feat he can't do in his own country due to the obstruction his group received from the industry.

There, the singer performed in front of 3600 fans in a yet another sold out concert, despite having to compete with Taiwan's Golden Horse Award ceremony.
