You had a sorrowful boyfriend that had 3 quadruple brothers and one younger brother and looked slightly different from the four.

You both were in high-school just two lovebirds.

One day he was on a trip to a museum with his brothers, he asked if he could invite you and they said sure, so you 6 were at the museum just looking around, but Karaku was checking you out, cuz he thought you were cute. Sekido: “KARAKU! STOP LOOKING AT HER LIKE THAT! SHES AIZETSU’S GF NOT YOURS!”
