Han Ji Eun, who released her newest track, "1234", earlier last month, has enlisted the help of The Cross Band for her promotions. The members of The Cross Band will be breaking their two year hiatus to perform live with Han Ji Eun for "1234".  The two have known each other through various musical activities for some time now, and with "1234" boasting a band style, there's no better time than now to embark on a collaboration. Han Ji Eun herself suggested the idea to perform together on stage, and the members readily agreed.  The pop love song features an acoustic guitar with an urban feel expressing the four symptoms of falling in love. Promotions will begin mid-October so stay tuned!
