Cause he was getting too cocky- shuraka already let it slide one time
But to let it slide again and to call shuraka beloved and say you love him WHILST fucking some other dude in front of him?? Yeah bsfr the ml dont want that-
Also I’m not sure if you peeped but the ml said that “it might’ve had worked with his father” so I think Pinky was the concubine for shurakas father but yeah
Pinky overstepped his place and the ml had to show clear boundaries that he wants nothing to do with him.
Pinkie technically belongs to Shuraka as the Padisha. He is part of the harem and thus cannot have just anyone in bed without the Padisha's consent. Most likely last night's activities were sanctioned by Shuraka who needed to observe the coupling so he knew what to do with Tei next time. But tonight, pinkie went behind his back fooling around with someone else trying to make Shuraka jealous/come to him like he used to do with the former Padisha, Shuraka's father. (Shuraka inherited the harem from his dad). Shuraka put him back in his place by making an example out of the lover. It's just politics and a clear message to everyone else not to fck with his and Tei's relationship

I don’t get it? Why kill the other guy
