I wouldn't mind that recommendation myself. But then we must define what is meant by "like Hillside"? What makes this VN itself? I'm guessing it's a combination of a "damsel in distress" theme, a bit of "The Bodyguard" movie setting, an emphasis on relationship building, a perfect renders, a cute female characters, an emotional involvement in the fate of the characters. It's funny that when I tried to find something similar using combination of tags from "Genre", I didn't find anything that gave me same vibes.
