No i dont think so i think the uke is realizing that there was someone who helped San's past lover someone else was remaining their side since uke came to earth after commiting a huge sin he thinks maybe he was also involved in whatever San's past lover was doing and got punished if that make sense (⌒▽⌒)
Is the uke the past lover or something? Why is the word 'again' in the synopsis?!
