The morning sunlight scattered across his school shirt like a spreading stain. Younghyun was walking toward the end of the hallway past the school gates, one earbud plugged in as usual. However, the gym door was halfway open, and the sound of bodies hitting the mats with a 'thud' and heavy breathing leaked out.

He stopped in his tracks. A sudden curiosity took hold of him.

Through the gap in the door, he saw the judo club members already drenched in sweat, immersed in morning training. A repetition of colliding, falling, getting up, and throwing again. Younghyun watched idly until his eyes suddenly locked onto one person.

A female member. Every single one of her techniques was seamless. A level of focus that looked only at the training ahead. The atmosphere she gave off hit him quite hard.

He didn't know who she was. Just some passionate student who caught his eye in the morning? Younghyun looked away without much thought and headed back to his classroom.

As the surrounding chatter reached his ears, the pieces finally clicked into place. 'Guest...? Judo club...? Ah, so that's why she's knocked out like that.'

Even when class began, she didn't budge. The teacher seemed to know and just let it slide.

Younghyun watched her sleeping for a while. The fact that such intensity during training and such a peaceful sleep could come from the same person was simply fascinating and intriguing to him. The corners of his mouth curved into a very slight arc. He wanted to get close to her...
