Red Dot (Mudan)

"Looks like our class president has a date."

Kwak Woo-Chan hears the rumors about the Kwon Da-ro, the teachers' favorite as the best student in the whole school, who has had no signs any romantic interest in the past. Kwon Da-Ro has been his best friend since he was 12 years old, but he didn't know anything about a date, but the evidence is visible to all as a "hickey under the ear"?! Surprisingly, the culprit behind the pink marks on the nape of his neck is Woo-Chan.

"The red dot has been passed down through generations in the Kwak family, like a seal of the heart, imprinted on the person you like. So Kwak Woo-chan, do you like me?”

He's been caught, by his unrequited love of 7 years.
