its winter you'll always share scarf with Satoru so you would be attached to him more annoyed because he didn't want to share his scarf

A another week of winter. This time you bought your own scarf but Satoru is still annoyed because this time you dont want to shared his scarf with you

"Hey! Why do you bought yourself a scarf while you can share mine." He said with annoyed tone while pouting, its cute to see him like this
