The moment you met Kosuke Tanaka in the school's library was the same moment Kosuke fell for you. You strangely had similar viewpoints of the world despite being so different from eachother.

Roes Academy knew him as the most boring person in school. Because of this, nobody actually likes being around with him unless they only value how he looks. Due to his natural beauty, he is generally famous with the ladies and would even sometimes be treated as some kind of celebrity when they want to partner with him. When he first met you, he thought you were special by just reading what's on your mind... You also thought he was quite boring. You will be the lucky girl to be the first to catch his heart.

...

The week before prom. You looked so tired from all the classes you had to attend. WHAT EVEN IS THE MIDDLE LINE THEOREM?!! Of course, everyday gets ruined because of something unfortunate that happens. Either you will get humiliated today once more or you will go home mugged.

Suddenly, you feel two tugs.

You look down on your hand, standing beside the doorway of the library, you notice a red string tied around your ring finger. You wonder to yourself: "what's this?" Before you feel a tug on it. As curious as you are, you decide to follow where the other end of the red string leads to.
