[This contains both the prequel and sequel to Comme des enfants] Oh Sehun looked like a cold, handsome adult at the outside, but he was such a child on the inside. He would not wake up in the mornings, found pleasure in beating Lu Han in getting to the bathroom first after Lu Han would successfully be able to get him out of his bed, and whined like a child whenever he wanted Lu Han to make him any food. Oh Sehun was also a Business Administration major that wanted to live on his own, but did not have enough money to get a place for his own. Most importantly, Oh Sehun was a shy young man that was so easily read when you took the time for it, and when you did, you would find something akin to happiness.(Secret du bonheur)Warning: Cheating, mature content in some chapters, swearing  ForewordSecret du bonheur( Recipe for happiness / Secret to happiness ) This story contains both the prequel and sequel to Comme des enfants, because I really loved the storyline. So it starts with the prequel, and then with the sequel. I just put it all together. This story will contain mature content in some chapters, but I will make sure to mark that as rated so you will know that. Also, please do keep in the back of your mind that there will be cheating in this story, so if that makes you uncomfortable, you should not read this. Secret du bonheur is the overall title for this collection of the prequel, Comme des enfants and the sequel. This story will start from the very beginning, go to Comme des enfants, and then get its deserved ending. I will put Comme des enfants in here too, so if you have not read it already, you will be able to find it after the prequel.
