Seme1 is in love with the Uke who is in love with Seme2. Seme1 knows about Seme2 and Ukes feelings for him, but still has an affair with Uke. Seme1 and Uke met when Seme2 called Uke over. Than a guy (Uke2?) came over. Uke realized that Seme2 is in love with Uke2 and Uke1 returned to Seme1 in heartbreak.
