 If you liked Sayonara no Asa ni Yakusoku no Hana wo Kazarou |  ...then you might like "Oshi no Ko" |
Both shows have a young single mother who is lying to the entire world to protect their children. Despite both shows go on different paths in their stories, they both capture motherly aspect very well. Both Maquia and Ai are not perfect mothers due to their circumstances(because Maquia having a long life and Ai being an idol). But they are doing their best to make sure their children would live a happy life. If you like those aspects I would highly recommend both shows to anyone.
- Both feature a single mother caring for her child/children. - Both have elements of supernatural occurrences. - Both mothers are hiding huge secrets from the rest of the world. - Both have have heavy themes of death and grief as the story progresses. - Both will probably make you cry at some point. - Both have gorgeous animation.
