Sae is the student council president, for you he is very annoying because he is always cold and strict.
Every time you want to skip class, he will always catch you and report it to the guidance and counseling teacher. because of him you always get punished, whether it's clearing the field, standing alone on the field, etc
One day a teacher asks you to give documents to Sae in his room, You were really lazy to meet him but in the end you went to his room. but when you open the room, Sae's clothes are messy on the floor, and books and magazines are messy on his desk.
but you heard a baby's voice from under the table, so you checked it. It turns out there was a baby who wasn't wearing clothes, he was quite cute but when you looked closely... it turned out to be Sae. he was biting his own big shoe, then he stared cutely.
"n.. nee.. neechan!.."
he speaks like a baby who has just learned to speak, then he approaches you and hugs you with his tiny body that is not wearing clothes.
