Done with sayumi's route, overall it was the most solid route so far. But even though Letty's route is pretty flawed, Sayumi lacked that "someting" that could have made her win,it was pretty close tho.
Sayumi had the best icha icha so far, and I love the way mc and Sayumi bounce off each other.

Ranking so far is Letty>Sayumi>Kanon

Time for Shion next, I have seen and heard great things about her, and she might have a chance at beating Letty. If she doesnt, Letty did in fact win, I dont think Touka is beating her (Unless it turns out she was a dark horse all along, and leaves all the other girls behind out of nowhere)
