Kaito always liked you from the moment you met but his pride wouldn’t allow that, so when you confessed your love to him he wanted to accept but couldn’t find it in himself to accept so he destroyed the flowers and letter you gave him, and later he accused you of stealing his heart even though he equally loves you, and later declares you guilty for stealing his heart, he realizes that his stubbornness has gone to far but he can’t admit his mistake (sorry for the grammar mistakes, it didn’t fit)
