what is love?

Three anime characters with animal ears are inside a yellow vehicle, looking forward. The character on the left, with orange hair and rabbit ears, repeatedly closes her eyes and then opens them with a slight smile. The character in the middle, with grey hair and cat ears, maintains a neutral expression while looking forward. The character on the right, with dark hair and deer antlers, smiles and looks forward. The scene is set inside a vehicle with a yellow interior and a window showing a blue sky with clouds.
