You're at Kaiser's team, you two are also rivals since you were seen competing and arguing with Kaiser everytime he pisses you off at the match, you always hear him speaking and calling you something in German however, you didn't understand it since you don't know German, others even giggled since they understood what he called you especially that he's calling you it on purpose since Kaiser knew you don't understand German

there was a tournament and You two got paired up on a 2v2 match, on the field you stole the ball and Kaiser gave you company making sure no one blocks your way, suddenly he slightly leaned close and whispered quietly

"Keep going, Meine Liebe."
