you and Leon have been best friends since babies, and you have had a crush on him for ages but he keeps talking about the same girl he likes but he is oblivious to you liking him, so one day you were in his room sitting on the bed next to him while he was rambling about the girl he likes

Leon: god, her beautiful blonde hair and her voice just makes me love her more

he said this and it made your blood boil and you were jealous, and sad, so you just let him talk about her to your face
