Its not a "age gap" its literally pedophilia and Aya was groomed. This author is known for predatory child and adult relationship stories. It's truly disgusting. Its not toxicity when theres a unbalanced power dynamic. It's unfortunate when the art was so good ╥﹏╥ it's really hard to find good yuri and shoujo ai ;(
well there is a more heartwarming story endou yasuko stalks the night where the mc endou (who looks like aya without glasses) is a much better character than her sire (who looks like sei and is a pos to three kids sound familiar?) when it comes to Haruki lookalike with glasses mc so it's kinda the reverse of what you see here and even though Endou has another potential love interest (who is eternal just like she) she chooses to watch over the Haruki lookalike at the end and her other lover has no objections because she understands her
i like the art and the story, but i also dont like is the age gap, and the toxicity ┑( ̄Д  ̄)┍
