Reina wrote on her blog that "During our tour we'll do original songs, too." this morning.
Makes it sound like they're mainly doing covers for their first tour. Which, in my opinion isn't weird at all considering Reina's schedule and all. Much easier for them to get into songs they already know than to learn a full 20+ original songs. That, along with the fact that they were just formed makes it okay imo. :3
But damn I swear, there better be SharanQ songs being performed on their tour or...
