This anime is absolutely adorable and deserves more recognition. While I get that it deviated from Ichikawa's original character concept as a psycho wanting to murder, I see that as a minor flaw. The plot it went with is doing exceptionally well. The pacing is perfect, with nothing feeling out of place, and the characters' feelings are completely justifiable.
What stands out is the female lead having a genuine personality and goals, unlike other romance anime where the female characters often revolve around being soulless dolls, limited to blushing and stuttering. The relationship between Ichikawa and Anna is just heartwarming. I appreciate how we get to witness their connection slowly develop, with Ichikawa evolving as a character.
The creators were somehow able to make it sweet but not cringe and also interesting
