The anticipation builds as Christmas approaches

A black-and-white manga panel shows a girl asking a boy if he's free on December 24th, causing him to react with shock and exclamation. The scene includes a speech bubble with 'HEY, UCHIKI-SENPAI.' and another with 'ARE YOU FREE ON DECEMBER 24TH?'. The boy's shocked face is accompanied by the sound effect 'THOOO! THIS IS!!'.
