It's super good-looking, but the extras are a little short. The young couple is really sweet. There are good and bad characters in it, all of them are quite distinct. The young couple love it very much.
Apart from the fact that it is a main story, there is nothing wrong with it. The plot is online, but there is very little plot, so it is like a non-CP story. I prefer the latter one. I hated physics at first, but finally fell in love with physics because of my favorite robot. I was even extremely lucky that I was extremely talented in physics and could see his lover again.
