Summary
Yasumasa Teratani serves as the best friend of Ichitaka, a character who possesses a somewhat nerdy appearance yet maintains an inflated sense of his own prowess with the opposite sex, despite his lack of actual romantic success. He frequently offers encouragement and advice to Seto, generally acting with good intentions even though his unsolicited help sometimes leads to unfortunate outcomes. When Seto fails to succeed, Teratani is visibly disappointed. Throughout the narrative, Ichitaka relies heavily on Teratani for guidance, but he gradually learns to become less dependent on him as the story progresses. Teratani is generally viewed as well-meaning, though he is also characterized as a jerk and a pervert, and is not considered particularly intelligent within the series.
