- Esoteric Happy Ending: Masamune's good ending. In order to relieve Koharu's guilt and free her from her perceived obligations, her friends get Nanami to wipe her memories and send her off with Masamune...without her permission or her having any agency over the choice, despite several routes emphasizing how horrible it was to forget.
- Relationship Writing Fumble: Mikoto's story path from the game was handled weirdly in the adaptation as the audiences were led to believe that the anime was going to adapt Sakuya's route and thus would have Mikoto end up with him based on the direction their relationship was going. Instead, she ends up with Natsuhiko, who, while arguably having the best chemistry and interesting relationship with her in the game and thus is the most preferred love interest for her among the fanbase, lacks most of the interactions and dialogue he has with Mikoto in the VN that made their romantic relationship interesting in the first place in the anime. So her ending up with him instead of Sakuya, whose relationship with her was more developed than Natsuhiko's in the anime, looked like it came out of nowhere to both anime-only viewers and VN fans.
- The Scrappy: Ron's commonly cited as one of the least appealing love interests. This ranges from the fact his route is seen as one of the weaker ones to his predatory behavior.
- They Wasted a Perfectly Good Character: Masamune. While generally liked, in his own route he's considered underwhelming for lacking the development or attention to backstory that the other love interests get. The fact his bad ending is the only one that's a joke ending played for laughs doesn't help, either
