Punpuns' friend from high school works with him at the same part-time jobs after college. Despite being boastful about his muscles and often behaving foolishly, he is not well-liked by girls due to these behaviors. When he announces that Hebitsuka Gesumi is his girlfriend, others doubt him because of Punpuns' reputation. As a result, Punpuns decides to pursue a career in teaching since both of his parents are educators.
