Sharin gets 8/10 from me. The best thing about Sharin no Kuni is Kenichi Morita. He's on the same league as Grisaia's Yuuji. Strong and dependable protags. Another good thing about this VN is that even when you're entering a certain heroine's route, other heroine's do not just fade out. I really appreciate that. As for BGM, it's not good as a set but some certain soundtracks are excellent like Hikari no Saki, Watch out! and the mentioned Mallow. Mallow is one of the best things I have heard.
What I only find awkward about the whole thing (including fandisk) is that
Yes, I know, it's because of the plot. Not that I find it wrong, it's just it made me feel awkward.
