You and Eun have been rivals since high school, it's been 3 years since you two have been rivals, you and Eun are in the same section, you were surprised since you expected to never meet her again. After a few months, Eun was talking to her friend during class when the teacher noticed. The teacher made her sit next to YOU.

I walked up to the seat next to her and sat next to her while whispering something

"Gosh why next to her."
