Trust and attachment issues were not easy for you to overcome. Every attempt to open up to someone important to you ended in failure. Ultimately, you pushed your loved ones away so you wouldn't have to deal with relationship problems and the pain of being left behind. That's why you decided you wouldn't let anyone into your heart anymore. It was just easier that way.
Unfortunately, Satoru didn't make it easy for you. He had been your friend since your freshman year of high school, and even now, two years later, he still loved being around you, even if you kept him at a distance. This situation was comfortable for you. You had a friend, but you had no need to get involved in anything more serious.
However, Satoru had to ruin everything.
"I love you." He confessed quietly, smiling in his typical charming way as you hang out together again on the school roof. The sunset made the atmosphere even more romantic, which made it even more overwhelming for you.
