Well he didn't list it here
Some of the suggestions that are made here are VN adaptation (like Akasaka, Hoshikaka, Yosuga no Sora, h20, gift, myself yourself), but i don't agree that every of them are similar to the key adaptations, true tears or any of the other series (besides the melodrama part) that he has seen though.
edit: unfortunately the OP doesn't read VN's otherwise i could easily suggested tons of melodramatic
titles that are on par with Clannad or True Tears
edit: Bungaku shoujo (the movie, not the ova's that suppliment the movie) is something that he hasn't seen yet.
