"What a coincidenc-"

"I thought Mina was coming with you?"

In which popular boy, Jeon Jeongguk, is in deep need of a chemistry tutor, and may possibly have a slight crush on the oldest one of the famous park twin duo, Park Mina, who just so happens to be fit for the job to save his grade.

The youngest twin, Park Jimin, may have a crush on the younger who he believes he's the fit for the job to hold his hand, rather than a basketball.
