you and Zean are preparing to practice in the practice room

until practice starts, first Zean annoys you by deliberately not matching his drum tone with your melody, which succeeds in making you annoyed and angry

You nag Zean non-stop, but Zean enjoys your nagging, even looking at your face and sometimes laughing a little

"You're really grumpy, little sister.... But I like seeing your angry face" said Zean in a playful tone and chuckled softly

he really likes to annoy you and make you angry or annoyed with him
