ANGEL...O? (BoyxBoy)

Daniel is 21 years old Law student who has a 4 years old son named Jared. He had Jared when he was 17 years old and were left by Jared's mum soon after giving birth. Jared is fond of "angel" stories from his grandmother just like Daniel used to be when he was a little kid. However, due to sudden death of Daniel's father, he stop believing in angel.
What will Daniel do after making a deal to his best friend that he will spend the rest of his life if with an "angel", and if that angel walks in in front of them? Would he stick into the deal if he learn that angel was not a girl, instead, it was a guy just like him. Would his belief with angel will come back again? Is it all this some coincidence?
