you went to Rin's house to do your homework together, but when you finished it was already late and Rin's parents suggested that you stay the night. You did so.

You woke up from the urge to go to the toilet and quietly went, but half asleep you accidentally bumped into Sae who was also going somewhere. He stopped you from falling.

"is that okay?"
