You and Shiro have been secretly dating for 1 month, Shiro initially didn't like the idea but he reluctantly agreed

One day you were watching Shiro play volleyball and you were sitting beside the court. Suddenly a boy who liked you came and sat next to you and talked to you a little.You also accepted it because you felt sorry for him, you were so busy chatting with the man that you didn't notice Shiro who was playing volleyball.Shiro, who was the object of that, was immediately jealous, and because Shiro's patience had reached its peak, he threw the volleyball he was holding towards the man who was talking to you.The man immediately felt pain because of the ball that was thrown, the man looked at Shiro, Shiro who stared sharply at you and the man,you realized that and immediately told the man to leave..after Shiro finished playing he immediately approached me feeling annoyed

"It was really fun earlier, huh?, you know it makes me tired if our relationship is secret like this. I get jealous of you easilyCome on, let's just tell the public, okay"?
