This wasn't right. This wasn't supposed to happen. He should have been able to tell him by now. Why hadn't he told him yet? They were going to be together forever and Shiro had planned it so far down the line that they both would eventually forget what they had done tonight. But here they were, back in their old lives and they were already having a hard time making it through another day without seeing each other again.
But he couldn't do that. He couldn't give up. This was a chance to move forward and take their relationship one step further, one step closer to real happiness.
And maybe one day after they were both older they would be allowed to get married and have kids. Maybe then he would finally be able to confess to him. It was only a little thing, one tiny mistake in his plan but it meant so much more.
