First of all, I wish Echizen boy a happy birthday. This is a birthday message for Echizen Ryoma...
"Junior" is the Japanese name for "junior high school sophomore". Chuunibyou literally means: some pathological self-awareness of teenagers in the second grade of junior high school. In fact, it is not limited to the second grade of junior high school, and it may not be considered a disease in the formal sense. Is this just a joke?
[But don't you think that the second grade of junior high school is the peak period for diseases? Of course, I don't rule out the first year of junior high school]
——"I am different from others."
——"It's not me who's wrong, it's the world."
——"This is maturity."
——"If there are counterexamples, please refer to the above three items."
As the saying goes, "If you don't reach the top of your class, your youth will be wasted." Everyone has a period of youth where he or she has the best of both worlds.
