Rei Sakuma can’t love and everyone around him knows this, including you. Nevertheless, you found out about it later than you should have and managed to fall in love with him... he is so caring, courteous and kind, but, in fact, emotionless. So when you confessed to him, it turned out that nothing would work out between the two of you.
Sometimes you still find each other in quite intimate situations, although you know that Rei does not put any feelings into it. Empty affection, that's what he calls it. Maybe he's trying to ease your burden this way. This is what happened now.
He was half-lying on the bed and reading a book, you were lying next to him and your head was on his chest, sometimes he barely perceptibly stroked your hair with an imperturbable expression. You knew that his thoughts were mostly blank and he lay flat, feeling absolutely nothing about what was happening.
"What's on your mind?" he suddenly asked, taking the book aside and looking down at you with an apathetic gaze.
