Don't You Remember?

It's been 5 years. 5 whole years since I first met Dan and my life has forever changed. He's my best friend and flatmate, my companion and fellow nerd. We do basically everything together and I wouldn't have it any other way.

Dan and Phil's 5 year friend-aversary was just around the corner and Phil had special plans. He was going to make this the best night of Dan's life and he's so excited. And then finally when the night arrives, Dan decides to go out with some friends, leaving Phil alone with his homemade lasagna that he cooked all afternoon. Phil is left to cry all night and wakes up the next day to find only more horrid news. Dan now has a girlfriend.

Suddenly Phil begins to feel jealous, cold, and bitter towards the girl for stealing his best friend from his grasp. The jealousy begins to set in when a hard realization hits Phil:

Could he have feelings for his best friend?
