A chaotic class of 10 MBTI types!
This was supposed to be a perfectly normal high school...
In the classroom, there's the overly free-spirited ENTP. The INTJ who wants everything to go according to plan. The ESFP who drags everyone into their pace. And a group of members who somehow cause an incident every single day.
Classes, breaks, after school, school festivals, romance, fights, and friendship—. It was supposed to be a normal youth, but with personalities this different, every day is an uproar!
"Do we really need to do that now?!" "No, this is just the kind of person I am." "Wait, someone stop them!!" "...Looks interesting, doesn't it?"
Values, vibes, and ways of thinking are all over the place.
An unpredictable school life brought to you by 10 people with very strong quirks.
What kind of days will you spend in this class?
