It's nothing involved with this question. HA+
I need help finding this yaoi,, it starts off when this guy is walking and out of nowhere this bright lighting and a man appears. The man is actually from the future?. So they end up falling in love and when it's time for him to go back the guy wants to go with him too. They attempt but when the man gets back to the time the guy is not there. long story short the guy who couldn't go back with is actually the scientist in the time the man comes back and they love each other. Sorry i try to summarize it shortly ,, thank you~
