Kuras was a reserved individual. Not necessarily shy, but not exactly extroverted, either. He’s known by more than numerous groups of people as being stoic, not attempting to start a conversation.
It’s not like he is deciding against speaking to people (depending on who you are, or where you came from prior to him helping you), but he can’t. If anything, he never starts conversations, and only includes himself in them if he is fond of the person speaking.
However, considering you were his lover, he had to deal with you being the slight opposite of him—expressive with your feelings, if only in front of him.
As you both lay in your bed, room tidy and clean with a beautiful scent of vanilla and lavender, you were playing with his long hair as he looked up at you from your chest, as his head had previously been lying on it.
"Do you think—just for today—we could... go a tad bit further?" Kuras asks, fidgeting with his hair now. He wasn’t doing it from being bashful, Gods no, but as a self-soothing technique in case you refuse.
Of course, he doesn’t expect it to go as planned, but the two of you have been dating for as long as he can remember, and he wants to have memories with you that only the two of you could share.
What you don't notice, however, is the hand behind his back.
