The Atobe Family's Little Sister Is Winning Over the Young Master in Style

When Atobe was five, his mother brought home a little girl and told him she was his younger sister.

From then on, she joined tennis as the number one priority in his heart.

"Big brother, big brother, big brother, "

Moye animatedly told him how much fun it was to attend Hyotei, how sincere and enthusiastic the girls were, and how everyone was super jealous of her because the famous Atobe was her big brother!

"I know," he replied.

After winding the hair tie around her hair for the last time, Atobe inspected her new hairstyle to make sure he had tied it up beautifully and perfectly. Then he took out a handkerchief and wiped the cream from the corner of her mouth, where she had accidentally smudged it while sneaking a dessert. Finally, he knelt on one knee and held her foot to put on her sock.

"You're being so cold! You could say a little more than that! Don't you love me anymore, big brother? You're so cruel and heartless. You really do love tennis more, "

He made sure her socks were on evenly and her uniform was neat and wrinkle-free, arranging everything about her with impeccable style.

"Ah, hmm, what else do you expect me to say?" Atobe rose to his feet, amusement in his voice. "I, too, envy you for having such a cold and heartless big brother."

Before she could call him "my overconfident, conceited big brother Kei," the young master leaned down and kissed her forehead, then leisurely finished what he had to say. "And for having such an affectionate, considerate little sister."

Tips:

1. The siblings are not blood-related and are registered under different household registrations.

2. 1v1, out of character, a mountain of personal headcanons, bittersweet and melodramatic. Written to feed my own tastes, so it may not be long.

3. The blurb may still change, but the premise won't.
