I'm looking for a manga I'm sure I've read on here but can't find. it's about a smaller seme with blonde hair and blue eyes if I'm correct and callboy uke with dark hair and red eyes. the uke also made the seme wait until he was 21 to be able to "buy" him and when the uke saw the semes dick he didn't want to have sex anymore. anyone know what this is???
