K-on!

A young girl with brown hair eats a corn dog in a dimly lit outdoor setting, her eyes closed in enjoyment. A boy with dark hair drinks from a soda bottle indoors, his eyes wide with surprise. A girl with long blonde hair plays a red electric guitar in a room with a fish tank, her expression shifting from focused to smiling. A group of students in winter clothing stand in a hallway, one girl in a yellow jacket smiling as she waves at the others.
