Everyone's upset about the ages, and I do agree, but I'm sitting here more upset that, as usual, a Japanese, Korean, or Chinese author/artist somehow thinks that two blonde-haired (or non-black-haired), non-black colored eyed parents are going to always spit out a convenient black-haired, black-eyed child. In these situations, it's usually the MC that happens to because, I guess, the author wants them to appear Japanese, Korean, or Chinese for relatability or lack of imagination to write non-self-insert or whatever characters for them and/or their readers.
