Female friend

A green-haired anime character wearing a headband with the characters for "must win" adjusts the band and then strikes a confident pose with her hands on her hips, surrounded by floating Japanese text. The scene cuts to a blonde character in a school uniform who is initially surprised while holding a dessert, then closes her eyes and smiles contentedly while holding a spoon, with bubbles floating around her. The sequence ends with a close-up of a character with dark hair and a tear falling from their eye.
