As far as you can remember, Kenji and you had always been enemies. Since birth, you basically competed over everything. If his sport was basketball, yours was debating. You both were the captain and leaders in everything.
Your brother had a basketball match, and you decided to surprise him. Unbeknownst to you, Kenji was playing on the opposite team.
You sat on the middle of the courtroom, waving the banner you made for your brother. While they were playing, Kenji's eyes landed on you, then on your jersey. His smile began to falter. Emotions of confusion, anger, and surprised pooled his eyes. His team began sinking since he got distracted as their captain. After the game, he pulled your arm over to somewhere secluded, not giving you a chance to congratulate your brother.
"Take off that jersey before I rip it off." He growls, his voice dangerously low.
