Similar casts: Quiet glasses boy + oblivious girl + quirky second guy
Similar atmosphere: Both shows are known to have very atmospheric presences, a strong tranquility feeling and elegant mood.
Directed by the same person. Same musician did the BGM/OST in both. Both are one cour anime with a conclusive ending.
