Mikaela and Yuuichirou both were orphans until a couple adopted them at the age of 4. Ever since they met, they became inseparable, everyone thought their love was sweet and innocent, brotherly, but it wasn't. At the age of 13 they discovered they were in love with each other; they became secret lovers until they would arrive at the age of 18 when they would be able to move out and be together, of course without their parents knowing about it. Everything would have turned out perfectly if it wasn't for their mother getting sick, as she got the news that she had cancer, she thought she wouldn't get to live long enough to see at least one of her sons get married, so in an act to fulfill his mother last long dream, Yuuichirou married his friend Shinoa Hiiragi, who had a crush on him for years. His mother was thrilled when she got the news of her son getting married, Yuu had everything planned out, when his mother would die,he would tell Shinoa the truth, well half of the truth that is, he would tell her he was gay and had only married her to make his mother happy on her death bed, he then would be able to live his life happily with his soul mate Mika, unfortunately for Yuu, a thing he didn't have planned happened; his mother beat the cancer. She was cured and now he was stuck in hell, he couldn't possibly divorce Shinoa, if his catholic homophobic mother would learn that he was gay, that both of her sons were gay, and on top of that, that they were in love with each other, it would make her have a heart attack and send her to the grave. No, Yuu couldn't do that to his mother, he loved her too much for that, he was too grateful for was she had done for him, for Mika, he couldn't throw those years away, even if that meant not having a happy ending until his mother died. Of course that didn't mean being miserable, he and Mika would have to maintain their relationship a secret for a little longer, but he would sure as hell not going to stop seeing Mika, he was maybe a fool but he was not an idiot.
As the time passed, Shinoa found strange that her husband didn't want to have sex with her, not even on their wedding night, he always claimed he was too tired or that he had work to do. So one day, Yuu decided that if he had to fake being in love with Shinoa, he would have to sleep with her eventually, but sleeping with her made him want to throw up so, one night he got drunk to be able to do it without actually throwing up on her, but because of how drunk he was, he forgot to put on a condom, and that was maybe the biggest mistake of his life. He had got Shinoa pregnant. Of course Mika was furious at Yuu, he couldn't believe his lover had been so careless, Yuu was at his last year of collage, he was only 20,he was going to be a lawyer he couldn't throw his life away life that, Mika had told him. Of course he was also jealous and mad because now it would be more complicated to divorce Shinoa when the time would come. That was the last time Shinoa and Yuu had sex, of course because they had a child it was easier to find excuses not to do it, he had managed to do it for 6 years. But now that their daughter was getting older it was harder to think of excuses…
