It depends upon the ending, plot quality (hey not all visual novels have that heavy plot) and how I can relate to it.
When I finished a visual novel, I try to look at all the routes and the choices I've made to get to the route. The choices might not be applicable in real life but it makes me think what are the choices I need for my life. If what I've read is a kinetic novel then I just look at is as a normal story.
