A few seconds ago…
'Wait, he leaves me alone here?' Yuki widened his eyes in surprise when he saw Kaito moving back to join the blocker line in the middle. 'What is wrong with him?!'
If it was anyone else, Yuki wouldn't be so dumbfounded like that. After all, it was easy for a player to forget the opponent who just did a block earlier, thinking that he would never be able to recover quickly enough to join the counterattack. However, Kaito was the one who always insisted on facing him and Riku head-on, and he knew that the boy was always waiting for the opportunity to humiliate him again. So, why would the boy leave him alone again here?
Of course, being confused was one thing, and wasting this golden opportunity was a completely different matter.
