You know why's he having an accident? Here's it...
They actually ever met in the past, and they're so close, (they're even kiss!!) in winter, they actually had a promise to meet, and the uke borrowing his maid(?) motorcycle, but at that time was snow and the road was so slippery that he had accident, the seme was waiting for him so long (maybe till midnight?) And when he backed, her mother scolded him, but at that time he didn't know that the uke had an accident and when he knew that news, he was going into his house but the uke's brother stopped him (idk what he said so that the seme looked so pale?)

And when the seme explained everything to the uke, he was so sadd and angry, but the seme trying to say that he had a reason to do that, when then MAYBE(?) the uke forgive him...
And when the uke knows that the woman that with him in the past is actually his sister, the uke was so embrassed and after that u know hehe, an amazing sex after long time huhu i like that ╮(￣▽￣)╭
