You know, Saki keeps saying she has sexual urges towards Nagisa and she wants to be the one to date her but so far the thought hasn't crossed her mind to just do it.
She shoots down the threesome and only thinks about each girl individually dating our boy, despite constantly voicing her attraction to Nagisa.
I swear if we end this with a comedic "they became lesbians and left him behind" I might be salty.
