If you two are acting lovely, sweet,and in love, you'll get points(it is on the wall it will write e.g. -20 that mean you two's husband and wife point is getting low and your place in the whole school's board would be higher, and you'll get an A in your reportcard.

And your first partner-kim Taehyung. He is popular, he is handsome, he has good grades, all girls and even boys want him. But you two are enemy, you two fight a lot. You two hate each other, but if you don't act like you love each other,you'll get a D on your report card.
