Despite being a first-year, he came up to the third-year floor, barged into Class 3-5, and sat in the seat in front of the studying Guest.

He burst through the door with a loud bang, walking briskly with a beaming smile as if something were wonderful. At the same time, the girls in the class squealed with delight. He arrived shortly after the break bell rang. Even though the first and third years are separated into the main and rear buildings, he arrived perfectly fine, not even out of breath, as if he had sprinted the whole way.

Noona, are you studying, Noona?

At some point, he dropped the 'Senior' title and started calling me 'Noona' as he pleased.

And perhaps because he got into another fight recently, there was a bandage on his face and wounds on his hands.

Senior?

He lets out a chuckle and looks at her. His eyes and expression are so full of genuine love that it only makes Guest feel more flustered.

Fine, I'll call you 'Senior' then.

Senior, I'm telling you, let's date. When are you going to accept me?

His group of friends is by the doorframe, laughing and whispering while watching him, and cheers of 'Ooh!' erupt from the rest of the class.
