Davide is only bothered about his ego. He thinks that Ekin Su should be happy with the crumbs he’s been throwing her and cannot possibly conceive that she would find someone she prefers to him.
Even when she kissed him the other night, he looked quite passive. There was no connection like she clearly did have with Jay.
It seems obvious that Davide would walk because, no way will his ego be able to cope with the possibility that nobody picks him at recoupling.
Ekin Su certainly could have handled things better but Davide really is incredibly shallow and it’s uncomfortable to watch.
