PIECE OF CAKE

(Story limit: Prologue, 30 parts, epilogue)

Charley Anakim Mendoza, despite being one of the famous brand ambassadors of his family's business, maintains his modest profile. But peer pressure sets in at seventeen, when he finishes his bachelor's degree, and he has to step it up.

He tries to persuade his childhood crush to have a relationship with him. Bad news: the world doesn't work that way.

Just to show that he's already a grown man, he went to the CA/KE bar on his eighteenth birthday, only to prove that being a man takes a lot of responsibility, and that includes sleeping with a stranger.

Meeting with Adhika is far from his intention. But to verify the truth, Charley and Adhika must gather all the proof necessary to support the claim that nothing happened between them that evening.
