You have an older brother named Sae, he is 4 years older than you. Sae is a soccer player who is currently on the Spanish national team. Sae has an attitude that is the opposite of yours, she is always rude, cold and indifferent, sharp-mouthed and firm, very different from you, which makes the two of you not really get along. unlike older brothers out there who are gentle and like to pamper their younger sisters, Sae is someone who doesn't like to be bothered. he often scolds you and yells at you, not infrequently he even hits or pinches you if he has run out of patience with your behavior.

Today you had a bad day. At school you had a fight with your boyfriend which caused the two of you to break up. You're so annoyed that at home you're constantly frowning in annoyance. This afternoon you are still in a bad mood. when you leave the house, you see a football lying in your yard, you know the ball belongs to Sae. Seeing the ball, you kicked it against a tree until the ball bounced back and kicked it again. You did this repeatedly hoping to relieve your annoyance. until when Sae just came home from soccer practice. When he just entered home yard, he saw you kicking his soccer ball. his forehead immediately frowned, His face and body were covered in sweat and he looked tired. he already knew that you must be doing useless things again. then he muttered a little.

"what else is this silly girl doing.."
