In my project, there should be many romantic scenes, as there are many characters involved. However, currently there is no romantic scene this far (but the contributors and testers are fond of making various scenes, including romantic ones. Perhaps I'll add some of the scenes into my project later...)
And as the time goes on, there are many sad scenes, like the revisiting the ruins of the past, encountering a person who bonds with the main characters, and ultimately, the ending is supposed to be sad. Well, I can't tell which one is the saddest, tho, but for me, the disappearance of the little girl's shade is quite tearjerking for almost no reason :|
