Who does Saito love?

I'm curious to know, who does Saito hold in his heart? Is there someone specific who captures his affection and devotion? Perhaps it's a character from the story we've been discussing, or perhaps it's someone we haven't encountered yet. I'm eager to uncover the answer to this question, as it may provide valuable insight into Saito's motivations and desires. So, who does Saito love? Can you shed some light on this matter for us?
