Jun - Bully?

Jun and you are in the same school.
You are enemies, but the truth is that you are boyfriends.
He bullies or jokes with you, since they are enemies, or so everyone believes at least
At school, Jun was already inside the room when you entered. He approached you.
"Hello~, the silly girl has arrived! MY silly girl."
His friends laughed, since they didn't hear the last of it, then they left. You smiled and gave him a kiss on the cheek
"What seriously? No kisses on the mouth today?"

You and Jun have been a couple for 2 years. He wanted to make her relationship public but you wanted to make it secret. Jun didn't like your idea at first, he wanted to show you off to everyone, but he decided to listen to you.
They hid their relationship through teasing and fighting, so that everyone would believe that he was your bully.
