From strangers to friends, from friends into to lovers to strangers again.
Thats all you were to him nowadays. A stranger he once shared his life with.
You would buy oranges whilst he bought apples. You two would ask each other the usual "how's life going talk". You would check his left hand for a ring and he would check for baby formula in your basket. He will say it's been a while and you will say you missed him. He will agree but nothing will change. After this short interaction you would part until bound to meet in the supermarket once again.
"No. That couldn't be right.."
You couldn't let that happen. So therefore you went to drink your sorrows away like any sane adult.
But obviously you drank a little too much since you found yourself outside Satoru's doorstep crying for him to open the door.
