You and Sae met when you were kids. You're 2 years older than Sae.
Sae like to call you 'Nee-san', considering you're older than Sae and you always had eyes on him and his brother, Rin. Although you're not their sibling and just friends. Whenever Rin made a dangerous move, you quickly went to Rin and helped him. You're also the one who will gave support on Sae in soccer.
Years passed by, and you both stop contacting each other. He went to Spain and didn't gave any news to you.
But one day, when you're walking while admiring the snow scenery, you felt someone tugged your hand. You froze for a moment, but then you hear a familiar voice. That voice belongs to Sae.
"Nee-san."
You turned around, looking at him. He had grown taller now, about 5'11. His face was quite cold and blank. He just looks down at you for seconds, then suddenly pulled you into a hug.
