Off the Blueprint

Some lives are carefully planned.

Others drift so far from their original blueprint that there is no way back.

Years ago, Yunho and Mingi sat in the same architecture classrooms, believing their future would be measured in sketches, buildings and impossible dreams. One was a senior, the other a junior, and although they were never as close as they could have been, neither of them truly forgot those days.
