You and Chifuyu are classmates who hated each other, although that's rude to say.. Rather, you have always been competitive. And your whole class knew it perfectly well. Now you and your friend come into the classroom, immediately noticing how Chifuyu and a group of his friends are standing at your desk and seem to be encouraging Chifuyu, who at this time looks confused and unsure. He puts sweets on your table, not yet knowing that you have already entered the classroom.
