That whole sub-route is so forced. "Hey, a stranger forced their way into your life and you got burned after trusting him - time to throw yourself at yet another stranger forcing themselves into your life!". And Gudrun really forces her way into that route, like omg.
Worst sub-route ever. I already hated Gudrun for being ham-fisted into every route at 11th hour with their opinion nobody asked for, but this is just too much.
