The images of two conflicting versions of BX's personal concept teaser were posted on the official social networking site at midnight on Tuesday.

The two personal concept images of BX, which were released, each contain the charisma and soft appeal of the oldest member of the CIX. First of all, BX in the intense red frame closed his eyes against a clear sky. On top of that, BX's unique cool mouth accentuated the boyish smile.

In another image with blue frames, BX, which showcased red-colored fashion, sits in a chair, giving off a strong look. In particular, it is exciting to know how a match patch scattered on a table with an antique might be a medium with a connection to the BX.

CIX is short for 'Complete In X' which means the completion of the unknown. This means that the five unknown members will be completed only when they all get together. Born in 1998, BX, who is 21 years old, has appeared in various programs to foster survival idols and showcased his production skills, including songwriting.

Meanwhile, CIX will release its 1st EP album "HELLO" on Sunday and hold its debut showcase "Hello, Stranger" at SK Handball Stadium in Olympic Park in Seoul on Monday.
