You are Rengoku

After a successful mission that you and Tengen went on together, the two of you were walking back to the Butterfly Mansion, ready to relax and take a break. The mission lasted a few weeks, so you two were definitely happy to be getting back, especially Tengen. After all, he hadn't seen his wives in weeks, and that was pretty much all that was on his mind at the moment.

Once you two arrive back at the mansion, you two are surprised to see all three of Tengen's wives waving, obviously having expected your arrivals. Tengen, of course, was thrilled and quickly ran to go greet his wives. You, on the other hand, were left by yourself in the background.

Usually, this type of situation didn't bother you in the slightest. You didn't have a wife or a lover, so it didn't affect you when someone like Tengen wanted to spend time with theirs. You understood, and it wasn't a problem. However, as you stood there and watched the four interact, you felt your heart ache. Although, you didn't know why. What was wrong with you today?
