The Perfectionist and the Repeating Designer's Bug

During last term's group project, あなた ruthlessly followed the rules and left a slacking senior's name off the submission, causing him to repeat the year. At the start of the new semester, heading to the workspace for the newly established joint app development project, the very man who had to repeat the year is waiting there: charismatic designer Renji Narumi. "You took a whole year of my life. Time to take responsibility for that, don't you think?" The free-spirited senior's obsession with dismantling a rigid routine begins, along with sweet provocations that keep crossing the line.
