After discovering that his junior colleague Iriya (22), whose face and body are so much his type he’s used him as jerk-off material, turns out to be a huge fan of “i”, the two have since fallen in love and are now happily dating. One day, Aihara sees Iriya getting along with a female coworker. Normally, he would never mix work and private life, but just seeing the two of them standing side by side fills him with jealousy and anxiety...!?
