i saw on the moegirl site that the birthdate of all main characters are specified to the year. For Fuutarou, we already know his birthday is on April 17. But moegirl also puts that he and the quintuplets are born in 2000. Can you confirm this?
This is a comment on 零奈 article. I see that you used the "Girl in the Photo" (照片中的孩子) image to depict a variation of this character. This is a problem because, in the manga, there's no proof that Rena and the Girl in the Photo are the same people. It's subtly implied that more than one of the quintuplets met Fuutarou in the past. You should consider this.
I'm an admin of the English 5Toubun no Hanayome Wikia. I wonder if you can understand English but I'll try anyway. I just found out your work on this Wikia and I'm extremely fascinated by it. Would you be interested in merging the two Wikia into a multi-language Wikia?
