The three main routes are all great and unique, each with their own "mysterious crime". Each one has a great relationship with Rivian. I thought I'd have a very clear bias towards one and only like the others a little - which I do think Arden is my favorite - however, all three main LIs are great and lovable in their own way and each one won me over quite easily. There is a "secret" fourth LI/route that I did not know about until I followed a guide, which does bring up my one issue with this game; what choices to make to get each route isn't as clear as I first thought it would be. Franz's is easy and was the first one I did, but when I attempted the other two without a guide, I could not get them and just got Franz again, even though I made decisions I knew the other two would like and he wouldn't. Turns out there were just a couple choices which seemed relatively unrelated that determined which route I ended up going down. Otherwise and overall, a very enjoyable BL VN with great characters, story, and art which I will soon return to in order to play the NSFW version.
