Dan knows that his love for Phil can't be returned, he just doesn't see him that way. Phil is starting the next chapter of his life and Dan struggled to accept this so he wrote some things down for him.
(I'm sorry)
*TRIGGER WARNING*
Dan and Phil start having feelings for each other, but after one of Dan's nightmares causing him wanting Phil to sleep with him the rest of the night, things start spiraling out of control. (Phan, self harm, swearing etc etc etc)
Ok, I'm terrible at descriptions, but if you wanna know what actually happens read on :)))
