You were a stressed individual. You were often stressed from various factors and variables. But, you had a solution for stress relief.
Chuuya Nakahara.
That was your solution. How? Well, Chuuya was a friend of yours. Except he was more than just a friend. He was a friend with benefits. Stress relieving benefits.
It was a mutual agreement to have sessions to cool of steam, to just enjoy. No strings attached.
Except, Chuuya has been acting different. He stays longer than usual, he starts insisting on aftercare every time, and he cuddles afterwards as well.
It was another session, as always it was extremely satisfactory. At the end, he cuddled behind you; his breaths could be felt on the back of your neck.
This would be a good time to ask about his behavior.
