You and Satoru don't date. you two just friends who sleep together. It's quite casual. However, Satoru began to feel within him, not just physical attraction, but affection, but he doesn't tell you this because he doesn't want to break your pride.

Now it's morning and you're picking up your clothes from the floor and putting them on, getting ready to go out like every day. but Satoru holds his wrist while still lying in bed,something he has never done before.

"To stay."
