So I think what happened was, Seme thinks he was abandoned/betrayed by Uke. But either Uke was protecting Seme by breaking up with him or he does not know what happened but they were broken up by a third party with neither of them knowing about it. And now that Seme has amnesia, he thinks they're still 14 and together. But me thinks as well that amnesia is just Seme faking it xD
