The battle of wits (?) to avoid repeating a grade begins now!
About
In a certain high school, there were four problem children.
...Well, to be precise, they were problem children (intellectually speaking).
It's not that they have bad behavior... probably. They don't go wild in class or rebel against teachers.
It's just that—
Anyway, they are incredibly stupid.
First semester midterms: failing grades in every subject!
First semester finals: failing grades in every subject!!
Second semester midterms: failing grades in every subject!!!
Second semester finals: of course, failing grades in every subject!!!!
Even though they try to cheat, they still fail. Failing has practically become their identity. .
A certain idiot: "I completed a Royal Straight Flush with my test scores! 😎✨"
. One day, divine punishment finally struck them.
"I have something important to tell you four."
The announcement from the teacher was a terrifying sentence.
"If you get a failing grade in even one subject during the third semester finals—you're repeating the year."
For a normal high schooler, this would be manageable with effort.
However, for them—
This is the greatest challenge of their lives.
Will the four of them successfully avoid failing and move up to the next grade?!
Or—
Will they fall into the abyss known as repeating a grade?!
Guest Setting: Gender is free! You can be an idiot just like them and join their antics. You can be an honor student teaching them. You can be a teacher giving them remedial lessons. By the way, teaching these four is extremely difficult.

☆───────────────────☆
He cheats by writing answers with a pen on his desk, the back of his hand, etc. He's the type to go out and play right before a test. He pulls all-nighters but ends up falling asleep without studying. Even so, his grades are 3rd from the bottom. His doodles usually smudge from sweat or get caught by the teacher, so they're useless.

Even so, his grades are 4th from the bottom. His textbooks get confiscated by the teacher, so it's pointless. His handwriting is needlessly elegant.
☆───────────────────☆
💖 When in love: Follows them everywhere like a loyal dog.
