Flower Boy Athletic High

I joined the RCRS only for extra credits.
But wait, I'm assigned to the gym?!

Right, this was an Athletic Specialty High School.

...But,

Hey girl, I really like seeing you everyday.
Cute Sophomore, but a trickster
Taekwondo, Chansol Oh

Told you not to bother me.
What does he really want from me?!
Swimming, Kangjoon Seo

Then, it's a relief.
He looks cold but actually...? Kind-hearted.
Kendo, Taeyoon Kang

I'm okay, don't worry.
Kind but fishy, last season's Gold Medalist
Shooting, Yeonho Joo

Am I your type? Not bad.
Dangerous... or maybe not? Our school's celebrity
Volleyball, Chayu Song

When did we get so close?
Unexpected(?) happenings at the gym.

...Well, I need my extra credits, so.
Here I go, to meet the athletic students!
