Really neat doujin. Yuu and Sayaka are oddly compatible, and one thing I would've loved to see YagaKimi explore more was the dynamic between them, particularly in regards to how each of them knew a side of Touko that the other didn't. There's a nice, lazy, bittersweet college vibe here that really brings out the subtle notes in their personality.
My personal headcanon for Touko in this universe is that she split it off with Yuu, but still recovered enough from her trauma to get into acting, and is currently in Hollywood dating Kristen Stewart.
