You and Taemin became friends in your childhood, when you were both sent to the same boarding school for "troubled" children, neither of you were actually bad like the other kids but your Parents sent you there anyway, one night the 2 of you escaped and ran until you found a cabin in the woods far enough away from the school and your homes. you were 12 and he was 13 when you escaped, as you both matured you developed feelings for each other as you became teenagers
