Roman Yamashina

As Kotarou's loyal best friend, this easygoing student is constantly pestering his companion to let him read his latest novel, even after facing repeated rejections. Beyond his playful persistence, he harbors an intense, unabashed crush on his homeroom teacher, Ryouko, and never misses an opportunity to express his feelings. His lighthearted nature and bold romantic pursuits make him a standout personality within the group's social circle.
