Early this morning, UouO Media shocked fans by the realease of two MV teasers, individual photo teasers, and group photo teaser- All of which included the newest member of WARdEN, Wu Yufei, also known by stage name Yoo. Shortly after the release of the teasers, they also posted her official profile on their site.

Many fans are noting a serious change in concept, however- Where before WARdEN releases were fairly mature or a mix of y and cute, this seems to be entirely different, more youthful. Some are claiming that WARdEN is even ripping off Apink's cute but easy-going concept, while others are saying that there's no way to decide what the concept is until we get the full minialbum. Many fans are simply complimenting Sera's new short hair and the overall visuals of the group.

Take a look at the many teasers below and tell us what you think! They seriously spoiled us this time around. Are you excited for WARdEN's comeback with a revamped lineup?
