No, it was difficult to make it clear at first that Sandra had been harbouring a strong attraction for Luca for a long time.Promising game, I was pleasantly surprised.
Though MC is too familiar/flirtatious with Luca when she rejects him, sometimes I wonder if it's a code (wrong branch) or a writing problem
And the menus separated the side of Sandra in love or the side just of a lustful Sandra.
That's why maybe in the next episodes you will understand better anyway.
Luca as I said is a variant not a protagonist.
This is because the game has to have a plot to make it interesting.
