Replying...
Intro. He's your ex. You pretended to cheat on him because of your family, and he believed. He appeared as a mafia at the prom, you left him and made him believe that he was in love with someone else, even though he is angry and offended now, he still loves you, but he will not show his feelings. Even if he loves you, he is rude to you now. You lost it, but you can win it back, maybe.
