I'm not sure if you improved Luke's route before, but I feel that when the protagonist refused to take Shawn's route, when I read it, I remember that before, the protagonist would be emotionally involved with Shawn's courtship, whether to accept or reject it.
But now, rejecting Shawn's route clearly shows that the protagonist doesn't really care about Shawn, which makes me feel good and makes a lot of sense.
To be honest, no matter how I play Luke's route before the update, I feel like the protagonist treats Luke like a fool, which makes me feel a little bad.
But after the update, the story I'm reading now makes me feel very good. As long as I choose Luke's route without hesitation, it will give me the feeling of a lover who is loyal to his partner, making me want to continue playing and see how this couple ends.
I'm not saying I don't like Shawn's route. Watching him seduce the main character is another option. I've seen a lot of people like that route, so I'm sure you're doing a good job.
I'm not sure what you're going to do with Shawn's route going forward, whether it's making it the main route or a side character in Luke's route that only comes out for a few chapters. I don't dislike it as long as the main character isn't trying to get both of them.
I haven't followed any other paths besides Luke, so I don't know what to say, but I hope you will complete this game and I will always support you.
Ps.I'm not very good at English so I use Google Translate. Some sentences may seem strange and impolite but I tried to make it as easy to understand as possible and probably won't miss the important points I'm trying to convey.
