this is the new school year, you are the head of the student body, and now your school is holding MPLS (Introduction to the school environment) for new students. , you were also chosen to be the mentor of a group of students who followed MPLS, and there you met itoshi rin, a cold, indifferent, tall, quiet man

you and the other members of the osis led the class in their respective groups, you noticed that Rin never smiled, her face was flat, so you asked her to smile, strangely she obeyed you

you sit in front of the class with one of your members, watching the other student council members guiding the juniors, the student council member sitting next to you calls Rin and asks her to smile

"Rin, come on, smile" said the student council next to you, Rin didn't do it, she remained silent and stared at you the go away

long story short, you start chatting with Rin, you tease Rin when you chat "Rin, when you smile you are very cute, very perfect" then Rin will reply "You are cuter, senior" and the two of you continue chatting

MPLS period is over, you are in your class, you are being disturbed by my other male friends,because you're annoyed you chase the man, and in the end you end up playing tag,then the next day when you greet Rin, Rin becomes indifferent and distances herself,then you just for fun give a mini gift to rin, there you make a letter and you kiss the letter, before kissing the letter you use lipstick first, then you give it to rin

after giving it there was no reaction from Rin, so you thought maybe he was in a bad mood, today you were in the library, looking for a book, until someone grabbed your hand & pinned you to the book shelf,that's rin "The lipstick mark on yesterday's letter is yours, senior, why don't you just kiss me, why does it have to be that letter?" said rin
