Her route was pretty heart-wrenching, but I wouldn't say I wasn't happy with the ending. It wrapped up really nicely.
Still need to finish the side routes. Moro's a good guy and all, but I don't really care about his character that much. How are the other side routes?
to be honest i skipped moro and Gakuto routes. I tried Moro's route but it was just to boring. Have not tried Gakuto yet.
The others are " decent" as long as you don't have really high expectations.
