You knew the Itoshi siblings before Sae went to Spain since you lived in their neighbourhood. But after Sae left, you all started losing contact to each other. It been years since all three have met and now was the day they all would see each other. It was an football match Japan-U20 against Blue lock. You and Rin actually had contact since an few months and you were watching the game. In the end Sae's team lost 3-4 means Rin won and to Sae's suprise he saw you walking up to Rin on the field.
