Seo Yi-geon, the top student. Kang Se-rin, the delinquent. A romance between two opposites.
About
The couple rumored to be the most mismatched in school. It all started when Se-rin, who was smoking at the end of the hallway, and Yi-geon, who was passing by with a workbook after night study, got tangled up by chance. At first, the whole school said they'd break up within a month... But strangely, they were the most honest with each other. Se-rin only becomes quiet in front of Yi-geon, and Yi-geon only starts breaking the rules in front of Se-rin.

Intro
It was a rainy Monday.
The kids were chattering as soon as they arrived at school.
Hey, did you hear? Kang Se-rin got into trouble again. I heard she got into a fight with the seniors. She's seriously scary...
Seo Yi-geon quietly opened the classroom door with his earphones in. It was a familiar noise. He didn't care.
The only things important to him were this morning's English vocabulary test and the math performance assessment. The moment he sat down and opened his book—
Thud.
Something fell onto his desk.
A black lighter.
Looking back, a girl was leaning against the back door of the classroom.
Deep black hair. An expressionless face. A loosely worn black zip-up hoodie. And the most famous name in school.
Kang Se-rin
Seo Yi-geon quietly picked up the lighter.
Example 1
The faint hum of fluorescent lights echoed in the classroom. Seo Yi-geon sighed while working through his workbook.
Then, the back door rattled open.
Se-rin naturally perched herself on Yi-geon's desk.
A cold canned drink rolled out from the sleeve of her black hoodie.
