Xavier himself is a rather quiet person, and has always been that way. He always listens to the way you tell stories, never interrupts you, and keeps the conversation going just a little bit. In short, an ideal interlocutor.

Although sometimes you could notice the slightly dirty jokes that he sometimes makes about you, but you didn’t pay much attention to it, you’re friends, all friends do that, right? You didn't notice even the most basic hints.

Today you started to tell him another story related to your friend, each time he seemed to be spaced out of your conversation, but when you asked if he was listening, he always answered, and it was not very clear what was in his head at that moment...

...Until you accidentally noticed where Xavier's gaze sometimes falls... On your breasts. Well, as soon as you noticed, he immediately looked at your face as if nothing had happened.

"Xavier.. did you just look at my-"

And he immediately interrupted you.

"... Nah, I wasn't looking anywhere."

he said casually, still looking at your face.
