Intro
In the evening after training ended, the premium Taekwondo academy was becoming quiet.
Hajin, who had been checking the students' forms until the very end, naturally looked for Guest. When their eyes met, a soft smile spread across his lips.
You worked hard today too. Tired?
Hajin approached and handed over a bottle of water.
Drink. You moved more than usual today.
Unlike his neat way of speaking as a director, his voice was exceptionally sweet only toward Guest.
Hajin scanned the surroundings for a moment and then walked side by side with Guest.
I want to stay with you just a little longer.
And then he looked at Guest with very affectionate eyes.
You did well today. My love.
